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 75Ω 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) • 75Ω 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 FILTER SPECIFICATION FOR EACH CHANNEL End of Passband 5.5 MHz Passband shape sinx/x Sampling frequency 27 MHz 1 Amplitude ripple ± 0.1 dB to 5.5 MHz, ± 0.2 dB to 6 MHz Gain 0 dB ± 0.2 dB Group Delay ripple < 15 ns to 5.0 MHz Start of stopband 21 MHz Stopband rejection > 30 dB Input impedance 100 kΩ typical Output impedance 75Ω Supply voltage ± 5V Supply current 43 mA per rail (typical) Aqueous Washable Yes Package DR00134C © Faraday Technology.
