VIDEO POST FILTER

SE121-00

4-CHANNEL OVERSAMPLED

The SE121-00 post filter is a surface mountable four channel video output filter designed to provide all the filtering and buffering requirements for the Analog Devices ADV7170 and ADV7171 encoders. Use of high performance video operational amplifiers gives minimal differential gain and phase distortion with the capability of driving up to ± 2.5V into 75W loads.

Other features:

	4 independent filtered channels for RGB and Alpha or dual S-video and dual composite.		accurate factory set gain of 0 dB (6 dB optional - order SE121-60)
	75W output termination resistors provided		Flat passband response - ADV encoder incorporates sinx/x correction
	high input impedance - makes interfacing easy		DC coupling eliminates tilt problems associated with AC coupling
	DC offset of encoder output (due to single rail operation) is corrected to bring blanking level near zero		24-pin surface mount DIL package
