| FMS6203 -- Low-Cost, 3-Channel Video Filter Driver for SD/PS/HD August 2007 FMS6203 Low-Cost, 3-Channel Video Filter Driver for SD/PS/HD Features Three Video Anti-Aliasing or Reconstruction Filters Supports Component YPrPb or RGB Video Three Channels, Selectable to 8MHz,16MHz, 32MHz for SD/PS/HD Applications Includes Wide Bandwidth Bypass Mode 6dB Gain Option Available for 150 Double Terminated Video Load 0dB Gain Option Available for High Impedance Loading Selectable Clamp or Bias Mode on Pb,Pr / B,R Inputs Inputs and Outputs can be either AC or DC Coupled DC-Coupled Outputs Eliminate Expensive Coupling Capacitors Output Disable Single 5V supply 2kV CDM / 8kV HBM ESD Protection Lead-Free TSSOP-14 Package 6th-Order Description The FMS6203 offers comprehensive filtering for set-top box or DVD applications. It is intended to replace passive LC filters and drivers with a low-cost integrated device. Filter channels are specialized for either component (YPbPr) or RGB video signals. These channels offer a selectable frequency response of 8, 16, or 32MHz. The filters can also be bypassed for high-frequency operation. Additional functionality of these channels includes input biasing mode and output disable. The FMS6203 may be driven directly by a DC-coupled DAC output or an AC-coupled signal. All inputs accept standard 1Vpp video signals. Each channel includes an output amplifier capable of driving a single (150) AC- or DC-coupled video load. All outputs can be disabled to save power in DC-coupled applications. The device is available in two factory-set options, a 0dB gain option and a 6dB gain option.

Fairchild offers a demonstration board to guide layout and aid device evaluation. The demo board is a fourlayer board with full power and ground planes. Following this layout configuration provides optimum performance and thermal characteristics for the device. For the best results, follow the steps and recommended routing rules listed below. Thermal Considerations Since the interior of most systems, such as set-topboxes, TVs, and DVD players are at +70C; consideration must be given to providing an adequate heat sink for the device package for maximum heat dissipation. When designing a system board, determine how much power each device dissipates. Ensure that devices of high power are not placed in the same location, such as directly above (top plane) and below bottom plane) each other on the PCB. Recommended Routing/Layout Rules Do not run analog and digital signals in parallel. Use separate analog and digital power planes to supply power. Traces should run on top of the ground plane at alltimes. No trace should run over ground/power splits. Avoid routing at 90-degree angles. Minimize clock and video data trace length differences. Include 10F and 0.1F ceramic power supply bypass capacitors. Place the 0.1F capacitor within 0.1 inches of the device power pin. Place the 10F capacitor within 0.75 inches of the device power pin. For multilayer boards, use a large ground plane to help dissipate heat. For two-layer boards, use a ground plane that extends beyond the device body by at least 0.5 inches on all sides. Include a metal paddle under the device on the top layer. Minimize all trace lengths to reduce series inductance. PCB Thermal Layout Considerations Understand the system power requirements and environmental conditions. Maximize thermal performance of the PCB. Consider using 70m of copper for high-power designs. Make the PCB as thin as possible by reducing FR4 thickness. Use vias in power pad to tie adjacent layers together. Remember that baseline temperature is a function of board area, not copper thickness. Modeling techniques can provide a first-order approximation.
