KIT ATION EVALU E AILABL AV
Dual, 10-Bit, 165Msps, Current-Output DAC
General Description
The MAX5854 dual, 10-bit, 165Msps digital-to-analog converter (DAC) provides superior dynamic performance in wideband communication systems. The device integrates two 10-bit DAC cores, and a 1.24V reference. The MAX5854 supports single-ended and differential modes of operation. The dynamic performance is maintained over the entire 2.7V to 3.6V power-supply operating range. The analog outputs support a -1.0V to +1.25V compliance voltage. The MAX5854 can operate in interleaved data mode to reduce the I/O pin count. This allows the converter to be updated on a single, 10-bit bus. The MAX5854 features digital control of channel gain matching to within 0.4dB in sixteen 0.05dB steps. Channel matching improves sideband suppression in analog quadrature modulation applications. The onchip 1.24V bandgap reference includes a control amplifier that allows external full-scale adjustments of both channels through a single resistor. The internal reference can be disabled and an external reference may be applied for high-accuracy applications. The MAX5854 features full-scale current outputs of 2mA to 20mA and operates from a 2.7V to 3.6V single supply. The DAC supports three modes of power-control operation: normal, low-power standby, and complete power-down. In power-down mode, the operating current is reduced to 1A. The MAX5854 is packaged in a 40-pin thin QFN with exposed paddle (EP) and is specified for the extended (-40C to +85C) temperature range. Pin-compatible, lower speed, and lower resolution versions are also available. Refer to the MAX5853 (10-bit, 80Msps), the MAX5852** (8-bit, 165Msps), and the MAX5851** (8-bit, 80Msps) data sheets for more information.

The MAX5854 dual, high-speed, 10-bit, current-output DAC provides superior performance in communication systems requiring low-distortion analog-signal reconstruction. The MAX5854 combines two DACs and an onchip 1.24V reference (Figure 2). The current outputs of the DACs can be configured for differential or singleended operation. The full-scale output current range is adjustable from 2mA to 20mA to optimize power dissipation and gain control. The MAX5854 accepts an input data and a DAC conversion rate of 165MHz. The inputs are latched on the rising edge of the clock whereas the output latches on the following rising edge. The MAX5854 features three modes of operation: normal, standby, and power-down (Table 2). These modes allow efficient power management. In power-down, the MAX5854 consumes only 1A of supply current. Wake-up time from standby mode to normal DAC operation is 3s.

An 8-bit control word routed through channel A's data port programs the gain matching, reference, and the operational mode of the MAX5854. The control word is latched on the rising edge of CW. CW is independent of the DAC clock. The DAC clock can always remain running, when the control word is written to the DAC. Table 1 and Table 2 represent the control word format and function. The gain on channel A can be adjusted to achieve gain matching between two channels in a user's system. The gain on channel A can be adjusted from -0.4dB to 0.35dB in steps of 0.05dB by using bits G3 to G0 (see Table 3).

Device Power-Up and States of Operation
At power-up, the MAX5854's default configuration is internal reference noninterleaved input mode with a gain of 0dB and a fully operational converter.

Clock Modes
The MAX5854 allows both single-ended CMOS and differential clock mode operation, and supports update rates of up to 165Msps. These modes are selected through an active-low control line called DCE. In singleended clock mode (DCE = 1), the CLK pin functions as an input, which accepts a user-provided single-ended clock signal. Data is written to the converter on the rising edge of the clock. The DAC outputs (previous data) are updated simultaneously on the same edge. If the DCE pin is pulled low, the MAX5854 will operate in differential clock mode. In this mode, the clock signal has to be applied to differential clock input pins CLKXP/CLKXN. The differential input accepts an input range of 0.5VP-P and a common-mode range of 1V to (CVDD - 0.5V), making the part ideal for low- input amplitude clock drives. CLKXP/CLKXN also help to minimize the jitter, and allow the user to connect a crystal oscillator directly to MAX5854.

Figure 4. MAX5854 with External Reference
The CLK pin now becomes an output, and provides a single-ended replica of the differential clock signal, which may be used to synchronize the input data. Data is written to the device on the rising edge of the CLK signal.
External Reference
To disable the internal reference of the MAX5854, set REN = 1. Apply a temperature-stable, external reference to drive the REFO pin and set the full-scale output (Figure 4). For improved accuracy and drift performance, choose a fixed output voltage reference such as the 1.2V, 25ppm/C MAX6520 bandgap reference.
Internal Reference and Control Amplifier
The MAX5854 provides an integrated 50ppm/C, 1.24V, low-noise bandgap reference that can be disabled and overridden with an external reference voltage. REFO serves either as an external reference input or an integrated reference output. If REN =0, the internal reference is selected and REFO provides a 1.24V (50A) output. Buffer REFO with an external amplifier, when driving a heavy load. The MAX5854 also employs a control amplifier designed to simultaneously regulate the full-scale output current (I FS ) for both outputs of the devices. Calculate the output current as: IFS = 32 IREF where I REF is the reference output current (I REF = VREFO / RSET) and IFS is the full-scale output current. R SET is the reference resistor that determines the amplifier output current of the MAX5854 (Figure 3). This current is mirrored into the current-source array where IFS is equally distributed between matched current segments and summed to valid output current readings for the DACs.
Detailed Timing
The MAX5854 accepts an input data and the DAC conversion rate of up to 165Msps. The input latches on the rising edge of the clock, whereas the output latches on the following rising edge. Figure 5 depicts the write cycle of the two DACs in noninterleaved mode. The MAX5854 can also operate in an interleaved data mode. Programming the IDE bit with a high level activates this mode (Tables 1 and 2). In interleaved mode, data for both DAC channels is written through input port A. Channel B data is written on the falling edge of the clock signal and then channel A data is written on the following rising edge of the clock signal. Both DAC outputs (channel A and B) are updated simultaneously on the next following rising edge of the clock. In interleaved data mode, the maximum input data rate per channel is half of the rate in noninterleaved mode. The interleaved data mode is attractive for applications where lower data rates are acceptable and interfacing on a single 10-bit bus is desired (Figure 6).

Applications Information
Differential-to-Single-Ended Conversion
The MAX5854 exhibits excellent dynamic performance to synthesize a wide variety of modulation schemes, including high-order QAM modulation with OFDM. Figure 7 shows a typical application circuit with output transformers performing the required differential-to-single-ended signal conversion. In this configuration, the MAX5854 operates in differential mode, which reduces even-order harmonics, and increases the available output power.
extend from 10MHz down to several hundred kilohertz. DC-coupling is desirable to eliminate long discharge time constants that are problematic with large, expensive coupling capacitors. Analog quadrature upconverters have a DC common-mode input requirement of typically 0.7V to 1.0V. The MAX5854 differential I/Q outputs can maintain the desired full-scale level at the required 0.7V to 1.0V DC common-mode level when powered from a single 2.85V (5%) supply. The MAX5854 meets this low-power requirement with minimal reduction in dynamic range while eliminating the need for level-shifting resistor networks.
Differential DC-Coupled Configuration
Figure 8 shows the MAX5854 output operating in differential, DC-coupled mode. This configuration can be used in communications systems employing analog quadrature upconverters and requiring a baseband sampling, dual-channel, high-speed DAC for I/Q synthesis. In these applications, information bandwidth can
Power Supplies, Bypassing, Decoupling, and Layout
Grounding and power-supply decoupling strongly influence the MAX5854 performance. Unwanted digital crosstalk can couple through the input, reference, power-supply, and ground connections, which can affect dynamic specifications, like signal-to-noise ratio

or spurious-free dynamic range. In addition, electromagnetic interference (EMI) can either couple into or be generated by the MAX5854. Observe the grounding and power-supply decoupling guidelines for highspeed, high-frequency applications. Follow the power supply and filter configuration to realize optimum dynamic performance. Use of a multilayer printed circuit (PC) board with separate ground and power-supply planes is recommended. Run high-speed signals on lines directly above the ground plane. The MAX5854 has separate analog and digital ground buses (AGND, CGND, and DGND, respectively). Provide separate analog, digital, and clock ground sections on the PC board with only one point connecting the three planes. The ground connection points should be located underneath the device and connected to the exposed paddle. Run digital signals above the digital ground plane and analog/clock signals above the analog/clock ground plane. Digital signals should be kept away from sensitive analog, clock, and reference inputs. Keep digital signal paths short and metal trace lengths matched to avoid propagation delay and data skew mismatch. The MAX5854 includes three separate power-supply inputs: analog (AV DD ), digital (DV DD ), and clock (CVDD). Use a single linear regulator power source to branch out to three separate power-supply lines (AVDD, DV DD , CV DD ) and returns (AGND, DGND, CGND). Filter each power-supply line to the respective return line using LC filters comprising ferrite beads and 10F capacitors. Filter each supply input locally with 0.1F ceramic capacitors to the respective return lines. Note: To maintain the dynamic performance of the Electrical Characteristics, ensure the voltage difference between DV DD , AV DD , and CV DD does not exceed 150mV. In this package, the data converter die is attached to an EP leadframe with the back of this frame exposed at the package bottom surface, facing the PC board side of the package. This allows a solid attachment of the package to the PC board with standard infrared (IR) flow soldering techniques. A specially created land pattern on the PC board, matching the size of the EP (4.1mm 4.1mm), ensures the proper attachment and grounding of the DAC. Designing vias* into the land area and implementing large ground planes in the PC board design allows for highest performance operation of the DAC. Use an array of 3 3 vias (0.3mm diameter per via hole and 1.2mm pitch between via holes) for this 40-pin thin QFN-EP package (package code: T4066-1).

Dynamic Performance Parameter Definitions
Adjacent Channel Leakage Ratio (ACLR) Commonly used in combination with wideband codedivision multiple-access (WCDMA), ACLR reflects the leakage power ratio in dB between the measured power within a channel relative to its adjacent channel. ACLR provides a quantifiable method of determining out-of-band spectral energy and its influence on an adjacent channel when a bandwidth-limited RF signal passes through a nonlinear device. Total Harmonic Distortion (THD) THD is the ratio of the RMS sum of all essential harmonics (within a Nyquist window) of the input signal to the fundamental itself. This can be expressed as: 2 2 2 2 V2 + V3 + V4 ... + ...VN THD = 20 x log V1
Thermal Characteristics and Packaging
Thermal Resistance 40-lead thin QFN-EP: JA = 38C/W The MAX5854 is packaged in a 40-pin thin QFN-EP package, providing greater design flexibility, increased thermal efficiency, and optimized AC performance of the DAC. The EP enables the implementation of grounding techniques, which are necessary to ensure highest performance operation.
where V1 is the fundamental amplitude, and V2 through VN are the amplitudes of the 2nd through Nth order harmonics. The MAX5854 uses the first seven harmonics for this calculation. Spurious-Free Dynamic Range (SFDR) SFDR is the ratio of RMS amplitude of the carrier frequency (maximum signal component) to the RMS value of their next-largest spectral component. SFDR is usually measured in dBc with respect to the carrier frequency amplitude or in dBFS with respect to the DAC's full-scale range. Depending on its test condition, SFDR is observed within a predefined window or to Nyquist.
*Vias connect the land pattern to internal or external copper planes. 16 ______________________________________________________________________________________
Dual, 10-Bit, 165Msps, Current-Output DAC
Multitone Power Ratio (MTPR) A series of equally spaced tones are applied to the DAC with one tone removed from the center of the range. MTPR is defined as the worst-case distortion (usually a 3rd-order harmonic product of the fundamental frequencies), which appears as the largest spur at the frequency of the missing tone in the sequence. This test can be performed with any number of input tones; however, four and eight tones are among the most common test conditions for CDMA- and GSM/EDGE-type applications. Gain Error A gain error is the difference between the ideal and the actual full-scale output current on the transfer curve, after nullifying the offset error. This error alters the slope of the transfer function and corresponds to the same percentage error in each step. The ideal current is defined by reference voltage at VREFO / IREF x 32. Settling Time The settling time is the amount of time required from the start of a transition until the DAC output settles to its new output value to within the converter's specified accuracy. Glitch Impulse A glitch is generated when a DAC switches between two codes. The largest glitch is usually generated around the midscale transition, when the input pattern transitions from 011...111 to 100...000. This occurs due to timing variations between the bits. The glitch impulse is found by integrating the voltage of the glitch at the midscale transition over time. The glitch impulse is usually specified in pV-s.
MAX5854
Intermodulation Distortion (IMD)
The two-tone IMD is the ratio expressed in dBc of either output tone to the worst 3rd-order (or higher) IMD products.
Static Performance Parameter Definitions
Integral Nonlinearity (INL) Integral nonlinearity (INL) is the deviation of the values on an actual transfer function from a line drawn between the end points of the transfer function, once offset and gain errors have been nullified. For a DAC, the deviations are measured at every individual step. Differential Nonlinearity (DNL) Differential nonlinearity (DNL) is the difference between an actual step height and the ideal value of 1 LSB. A DNL error specification no more negative than -1 LSB guarantees monotonic transfer function.
