12-Bit, 80 MSPS, High Speed Video D/A Converter
Description
The HI5735 is a 12-bit, 80 MSPS, D/A converter which is implemented in the Intersil BiCMOS 10V (HBC-10) process. Operating from +5V and -5.2V, the converter provides -20.48mA of full scale output current and includes an input data register and bandgap voltage reference. Low glitch energy and excellent frequency domain performance are achieved using a segmented architecture. The digital inputs are TTL/CMOS compatible and translated internally to ECL. All internal logic is implemented in ECL to achieve high switching speed with low noise. The addition of laser trimming assures 12-bit linearity is maintained along the entire transfer curve.

Detailed Description
The HI5735 is a 12-bit, current out D/A converter. The DAC can convert at 80 MSPS and runs on +5V and -5.2V supplies. The architecture is an R/2R and segmented switching current cell arrangement to reduce glitch. Laser trimming is employed to tune linearity to true 12-bit levels. The HI5735 achieves its low power and high speed performance from an advanced BiCMOS process. The HI5735 consumes 650mW (typical) and has an improved hold time of only 0.25ns (typical). Digital Inputs The HI5735 is a TTL/CMOS compatible D/A. Data is latched by a Master register. Once latched, data inputs D0 (LSB) thru D11 (MSB) are internally translated from TTL to ECL. The internal latch and switching current source controls are implemented in ECL technology to maintain high switching speeds and low noise characteristics. Decoder/Driver The architecture employs a split R/2R ladder and Segmented Current source arrangement. Bits D0 (LSB) thru D7 directly drive a typical R/2R network to create the binary weighted current sources. Bits D8 thru D11 (MSB) pass thru a "thermometer" decoder that converts the incoming data into 15 individual segmented current source enables. This split architecture helps to improve glitch, thus resulting in a more constant glitch characteristic across the entire output transfer function. Clocks and Termination The internal 12-bit register is updated on the rising edge of the clock. Since the HI5735 clock rate can run to 80 MSPS,
HI5735 DAC ZO = 50 CLK RT = 50
to minimize reflections and clock noise into the part, proper termination should be used. In PCB layout clock runs should be kept short and have a minimum of loads. To guarantee consistent results from board to board, controlled impedance PCBs should be used with a characteristic line impedance ZO of 50. To terminate the clock line, a shunt terminator to ground is the most effective type at a 80 MSPS clock rate. A typical value for termination can be determined by the equation: RT = ZO , for the termination resistor. For a controlled impedance board with a ZO of 50, the RT = 50. Shunt termination is best used at the receiving end of the transmission line or as close to the HI5735 CLK pin as possible.
FIGURE 10. CLOCK LINE TERMINATION
Rise and Fall times and propagation delay of the line will be affected by the Shunt Terminator. The terminator should be connected to DGND.

Noise Reduction To reduce power supply noise, separate analog and digital power supplies should be used with 0.1F and 0.01F ceramic capacitors placed as close to the body of the HI5735 as possible on the analog (AVEE) and digital (DVEE) supplies. The analog and digital ground returns should be connected together back at the device to ensure proper operation on power up. The VCC power pin should also be decoupled with a 0.1F capacitor. Reference The internal reference of the HI5735 is a -1.23V (typical) bandgap voltage reference with 50V/oC of temperature drift (typical). The internal reference is connected to the Control Amplifier which in turn drives the segmented current cells. Reference Out (REF OUT) is internally connected to the Control Amplifier. The Control Amplifier Output (CTRL OUT) should be used to drive the Control Amplifier Input (CTRL IN) and a 0.1F capacitor to analog VEE . This improves settling time by providing an AC ground at the current source base node. The Full Scale Output Current is controlled by the REF OUT pin and the set resistor (RSET). The ratio is: IOUT (Full Scale) = (VREF OUT /RSET) x 16. The internal reference (REF OUT) can be overdriven with a more precise external reference to provide better performance over temperature. Figure 11 illustrates a typical external reference configuration.

Settling Time The settling time of the HI5735 is measured as the time it takes for the output of the DAC to settle to within a 1/2 LSB error band of its final value during a full scale (code 0000... to 1111.... or 1111... to 0000...) transition. All claims made by Intersil with respect to the settling time performance of the HI5735 have been fully verified by the National Institute of Standards and Technology (NIST) and are fully traceable. Glitch The output glitch of the HI5735 is measured by summing the area under the switching transients after an update of the DAC. Glitch is caused by the time skew between bits of the incoming digital data. Typically, the switching time of digital inputs are asymmetrical, meaning that the turn off time is faster than the turn on time (TTL designs). Unequal delay paths through the device can also cause one current source to change before another. In order to minimize this, the Intersil HI5735 employes an internal register, just prior to the current sources, which is updated on the clock edge. Lastly, the worst case glitch on traditional D/A converters usually occurs at the major transition (i.e., code 2047 to 2048). However, due to the split architecture of the HI5735, the glitch is moved to the 255 to 256 transition (and every subsequent 256 code transitions thereafter). This split R/2R segmented current source architecture, which decreases the amount of current switching at any one time, makes the glitch practically constant over the entire output range. By making the glitch a constant size over the entire output range, this effectively integrates this error out of the end application. In measuring the output glitch of the HI5735 the output is terminated into a 64 load. The glitch is measured at any one of the current cell carry (code 255 to 256 transition or any multiple thereof) throughout the DACs output range. The glitch energy is calculated by measuring the area under the voltage-time curve. Figure 13 shows the area considered as glitch when changing the DAC output. Units are typically specified in picoVolt-seconds (pV-s).

FIGURE 11. EXTERNAL REFERENCE CONFIGURATION
Outputs The outputs IOUT and IOUT are complementary current outputs. Current is steered to either IOUT or IOUT in proportion to the digital input code. The sum of the two currents is always equal to the full scale current minus one LSB. The current output can be converted to a voltage by using a load resistor. Both current outputs should have the same load resistor (64 typically). By using a 64 load on the output, a 50 effective output resistance (ROUT) is achieved due to the 227 (15%) parallel resistance seen looking back into the output. This is the nominal value of the R2R ladder of the DAC. The 50 output is needed for matching the output with a 50 line. The load resistor should be chosen so that the effective output resistance (ROUT) matches the line resistance. The output voltage is: VOUT = IOUT x ROUT . IOUT is defined in the reference section. IOUT is not trimmed to 12 bits, so it is not recommended that it be used in conjunction with IOUT in a differential-to-single-ended application. The compliance range of the output is from -1.25V to 0V, with a 1VP-P voltage swing allowed within this range.

Definition of Specifications
Integral Linearity Error, INL, is the measure of the worst case point that deviates from a best fit straight line of data values along the transfer curve. Differential Linearity Error, DNL, is the measure of the error in step size between adjacent codes along the converter's transfer curve. Ideally, the step size is 1 LSB from one code to the next, and the deviation from 1 LSB is known as DNL. A DNL specification of greater than -1 LSB guarantees monotonicity.
GLITCH ENERGY = (a x t)/2
a (mV)
Feedthru, is the measure of the undesirable switching noise coupled to the output. Output Voltage Full Scale Settling Time, is the time required from the 50% point on the clock input for a full scale step to settle within an 1/2 LSB error band. Output Voltage Small Scale Settling Time, is the time required from the 50% point on the clock input for a 100mV step to settle within an 1/2 LSB error band. This is used by applications reconstructing highly correlated signals such as sine waves with more than 5 points per cycle. Glitch Area, GE, is the switching transient appearing on the output during a code transition. It is measured as the area under the curve and expressed as a picoVolt*Time specification (typically pV*s). Differential Gain, AV , is the gain error from an ideal sine wave with a normalized amplitude. Differential Phase, , is the phase error from an ideal sine wave.

FIGURE 13. MEASURING GLITCH ENERGY
To convert the output of the HI5735 to a bipolar 4V swing, the following applications circuit is recommended. The reference can only provide 125A of drive, so it must be buffered to create the bipolar offset current needed to generate the -2V output with all bits "off". The output current must be converted to a voltage and then gained up and offset to produce the proper swing. Care must be taken to compensate for the voltage swing and error

Signal to Noise Ratio, SNR, is the ratio of a fundamental to the noise floor of the analog output. The first 5 harmonics are ignored, and an output filter of 1/2 the clock frequency is used to eliminate alias products. Total Harmonic Distortion, THD, is the ratio of the DAC output fundamental to the RMS sum of the harmonics. The first 5 harmonics are included, and an output filter of 1/2 the clock frequency is used to eliminate alias products. Spurious Free Dynamic Range, SFDR, is the amplitude difference from a fundamental to the largest harmonically or non-harmonically related spur. A sine wave is loaded into the D/A and the output filtered at 1/2 the clock frequency to eliminate noise from clocking alias terms. Intermodulation Distortion, IMD, is the measure of the sum and difference products produced when a two tone input is driven into the D/A. The distortion products created will arise at sum and difference frequencies of the two tones. IMD can be calculated using the following equation:
