As part of continual product improvement the specifications, details and dimensions shown in this publication are subject to change without notice FARA085d Page 1 of 2 Aug-05(C) 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 Amplitude ripple1 ± 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 SE120-00 4-CHANNEL OVERSAMPLED POST FILTERS
