SGM9111 features a dc-coupled input buffer, a 5-pole low-pass filter to eliminate out-of-band noise of video enc oder, and a gain of 6db in the output amplifier to drive 75 ? load. the ac- or dc-coupled input buffer eliminat es sync crush, droop, and field tilt. the output of SGM9111 also can be dc-coupled or ac-coupled. input considerations besides ac coupling, the SGM9111 inputs also can be dc-coupled. in dc coupling application, no input coupling capacitors are needed because the amplitude of input video signal from dac includes ground and extends up to 1.4v, and SGM9111 can be directly connected to the output of a single-supply, current-output dac without any external bias network. in applications where dac?s output level exceeds the range from 0v to 1.4v, or SGM9111 is driven by an unknown external source or a scart switch which has its own clamping circuit, ac coupling is needed. output considerations the SGM9111 outputs can be dc-coupled or ac-coupled. when input is 0v, the SGM9111 output voltage is 340mv typically. in dc coupling design, one 75? resistor is used to connect SGM9111?s output pin with external load directly, and this serial back- termination resistor is used to match the impedance of the transmission line between SGM9111 and external load to cancel the signal reflection. the SGM9111 outputs can sink and source current allowing the device to be ac-coupled with external load. in ac coupling, at least 220f capacitor will be used in order to eliminate field tilt. power-supply bypassing and layout correct power supply bypassing is very important for optimizing video performance in design. one 0.1f and one 10f capacitors are always used to bypass v cc pin of SGM9111. place these two capacitors as close to the SGM9111 supply pin as possible. a large ground plane is also needed to ensure optimum performance. the input and output termination resistors should be placed as close to the related pins of SGM9111 as possible to avoid performance degradation. the pcb traces at the output side should have 75 ? characteristic impedance in order to match the 75 ? characteristic impedance of the cable connecting external load. in design, keep the board trace at the inputs and outputs of the SGM9111 as short as possible to minimize the parasitic stray capacitance and noise pickup.
