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, 32, or 65MHz. Additional functionality of these channels includes input biasing mode and output disable. The FMS6303 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 DCcoupled applications.

Fairchild offers an evaluation board to guide layout and aid device evaluation. The evaluation board is a four-layer 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. Recommended Routing / Layout Rules Do not run analog and digital signals in parallel. Use separate analog and digital power planes to supply power. Run traces on top of the ground plane at all times. Do not run traces 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 multi-layer 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. Consider 70m copper for high-power designs. Make the PCB as thin as possible by reducing FR4 thickness. Use vias in the power pad to tie adjacent layers together. Remember that baseline temperature is a function of board area, not copper thickness. Use modeling techniques for first-order approximation. Output Considerations The FMS6303 outputs are DC offset from the input by 150mV; therefore, VOUT = 2*VIN DC+150mV. This offset is required to obtain optimal performance from the output driver and is held at the minimum value to decrease the standing DC current into the load. Since the FMS6303 has a 2x (6dB) gain, the output is typically connected via a 75-series back-matching resistor followed by the 75 video cable. Because of the inherent divide by two of this configuration, the blanking level at the load of the video signal is always less than 1V. When AC-coupling the output, ensure that the coupling capacitor of choice passes the lowest frequency content in the video signal and that line time distortion (video tilt) is kept as low as possible. The selection of the coupling capacitor is a function of the subsequent circuit input impedance and the leakage current of the input being driven. To obtain the highest quality output video signal, the series termination resistor must be placed as close to the device output pin as possible. This greatly reduces the parasitic capacitance and inductance effect on the FMS6303 output driver. Recommended distance from device pin to place series termination resistor is no greater than 0.1 inches. Thermal Considerations Since the interior of most systems, such as set-top boxes, 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. PCB Thermal Layout Considerations Understand the system power requirements and environmental conditions. Maximize thermal performance of the PCB. Figure 13.
