Data Sheet September 21, 2006 FN6277.0
YC to Composite Video Driver with LPF
The ISL59116 is a YC reconstruction filter with a -3dB roll-off frequency of 9MHz and summer amplifier to create the composite video signal. Operating from single supplies ranging from +2.5V to +3.6V and drawing only 4.6mA quiescent current, the ISL59116 is ideally suited for low power, battery-operated applications. Additionally, an enable high pin shuts the part down in under 14ns. The ISL59116 is designed to meet the needs for very low power and bandwidth required in battery-operated communication, instrumentation, and modern industrial applications such as video on demand, cable set-top boxes, MP3 players, and HDTV. The ISL59116 is offered in a space-saving WLCSP chipscale package guaranteed to a 0.57mm maximum height constraint and specified for operation from -40C to +85C temperature range.

ISL59116 Application Information
The ISL59116 is a single-supply rail-to-rail triple (two in, three out) video amplifier with internal sync tip clamps, a typical -3dB bandwidth of 9MHz and slew rate of about 40V/s. The Y and C channels are internally mixed to create a third CVBS (composite) video output. This part is ideally suited for applications requiring high composite and S-video performance with very low power consumption. As the performance characteristics and features illustrate, the ISL59116 is optimized for portable video applications.
Output Drive Capability
The ISL59116 does not have internal short circuit protection circuitry. If the output is shorted indefinitely, the power dissipation could easily overheat the die or the current could eventually compromise metal integrity. Maximum reliability is maintained if the output current never exceeds 40mA. This limit is set by the design of the internal metal interconnect. Note that for transient short circuits, the part is robust. Short circuit protection can be provided externally with a back match resistor in series with the output placed close as possible to the output pin. In video applications this would be a 75 resistor and will provide adequate short circuit protection to the device. Care should still be taken not to stress the device with a short at the output.
Internal Sync Clamp
Embedded video DACs typically use ground as their most negative supply. This places the sync tip voltage at a minimum of 0V. Presenting a 0V input to most single supply amplifiers will saturate the output stage of the amplifier resulting in a clipped sync tip and degraded video image. The ISL59116 features an internal sync clamp and offset function that level shifts the entire video signal to the optimum level before it reaches the amplifiers' input stage. These features also help avoid saturation of the output stage of the amplifier by setting the signal closer to the best voltage range. The simplified block diagram on the front page shows the basic operation of the ISL59116's sync clamp. The Y input's AC-coupled video sync signal is pulled negative by a current source at the input. When the sync tip goes below the comparator threshold, the comparator output goes high, pulling up on the Y input through the diode, forcing current into the coupling capacitor until the voltage at the Y input is again 0V, and the comparator turns off. This forces the sync tip clamp to always be 0V, setting the offset for the entire video signal.
Power Dissipation
With the high output drive capability of the ISL59116, it is possible to exceed the +125C absolute maximum junction temperature under certain load current conditions. Therefore, it is important to calculate the maximum junction temperature for an application to determine if load conditions or package types need to be modified to assure operation of the amplifier in a safe operating area. The maximum power dissipation allowed in a package is determined according to:
T JMAX - T AMAX PD MAX = ------------------------------------------- JA
Where: TJMAX = Maximum junction temperature TAMAX = Maximum ambient temperature JA = Thermal resistance of the package The maximum power dissipation actually produced by an IC is the total quiescent supply current times the total power supply voltage, plus the power in the IC due to the load, or: for sourcing:
V OUT PD MAX = V S x I SMAX + ( V S - V OUT ) x --------------R
L
The Sallen Key Low Pass Filter
The Sallen Key is a classic low pass configuration. This provides a very stable low pass function, and in the case of the ISL59116, a three-pole roll-off at 9MHz. The three-pole function is accomplished with an RC low pass network placed in series with and before the Sallen Key. The first pole is formed by an RC network, with poles two and three generated with a Sallen Key, creating a nice three-pole roll-off at 9MHz.
Output Coupling
The ISL59116 can be AC or DC coupled to its output. When AC coupling, a 220F coupling capacitor is recommended to ensure that low frequencies are passed, preventing video "tilt" or "droop" across a line. The ISL59116's internal sync clamp makes it possible to DC couple the output to a video load, eliminating the need for any AC coupling capacitors, saving board space, cost, and eliminating any "tilt" or offset shift in the output signal. The trade off is larger supply current draw, since the DC component of the signal is now dissipated in the load resistor. Typical load current for AC coupled signals is 5mA compared to 10mA for DC coupling. 8
for sinking:
PD MAX = V S x I SMAX + ( V OUT - V S ) x I LOAD
Where: VS = Supply voltage ISMAX = Maximum quiescent supply current VOUT = Maximum output voltage of the application RLOAD = Load resistance tied to ground ILOAD = Load current

Power Supply Bypassing Printed Circuit Board Layout
As with any modern operational amplifier, a good printed circuit board layout is necessary for optimum performance. Lead lengths should be as short as possible. The power supply pin must be well bypassed to reduce the risk of oscillation. For normal single supply operation, a single 4.7F tantalum capacitor in parallel with a 0.1F ceramic capacitor from VS+ to GND will suffice.
Printed Circuit Board Layout
For good AC performance, parasitic capacitance should be kept to minimum. Use of wire wound resistors should be avoided because of their additional series inductance. Use of sockets should also be avoided if possible. Sockets add parasitic inductance and capacitance that can result in compromised performance.
