Data Sheet April 4, 2007 FN6432.1
Triple Channel Video Driver with LPF
The ISL59123 is a triple channel reconstruction filter with a -3dB roll-off frequency of 18MHz. Operating from single supplies ranging from +2.5V to +3.6V and sinking a low 4mA quiescent current, the ISL59123 is ideally suited for low power, battery-operated applications. An enable pin allows the part to be placed in a 500nA shutdown mode in less than 30ns. The ISL59123 is designed to meet the needs for extremely low power and bandwidth requirements in battery-operated communication, instrumentation, and modern industrial applications such as video on demand, cable set-top boxes, MP3 players, and HDTV. The ISL59123 is offered in a space-saving chipscale package guaranteed to a 0.57mm maximum height constraint and specified for operation from -40C to +85C temperature range.

ISL59123 Application Information
The ISL59123 is a single-supply rail-to-rail triple video lowpass filter and amplifier with a -3dB bandwidth of 18MHz. It provides anti-aliasing for component, s-video, and composite video signals. Its small size and low power make the ISL59123 ideal for portable video applications. 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 use Equation 2:
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 ISL59123, a three-pole roll-off at 18MHz. 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 (including the impedance of the source driving the ISL59123), with poles two and three generated by a Sallen Key, creating a three-pole roll-off characteristic at 18MHz.
(EQ. 2)
for sinking use Equation 3:
PD MAX = V S x I SMAX + ( V OUT - V S ) x I LOAD (EQ. 3)
Output Coupling
The ISL59123 can be AC or DC coupled to its output. When AC coupled, a 220F coupling capacitor is recommended to ensure that low frequencies are passed, preventing video "tilt" or "droop" across a line.
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
Output Drive Capability
The ISL59123 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.
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 VDD 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.
Power Dissipation
With the high output drive capability of the ISL59123, 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 Equation 1:
T JMAX - T AMAX PD MAX = ------------------------------------------- JA (EQ. 1)
