4-CHANNEL OVERSAMPLED
POST FILTERS
SE120-00
The SE120-00 4-channel oversampled post filter is a surface mountable four channel video output filter
designed to provide all the filtering and buffering requirements for the Fairchild/Raytheon TMC2192/93
encoder. Use of high performance video operational amplifiers gives minimal differential gain and phase
distortion with the capability of driving up to ± 2.5V into 75⦠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 SE120-60)
⢠75⦠output termination resistors provided
⢠sinx/x correction for 27 MHz sampling plus compensation for the encoder roll-off
⢠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
