As part of continual product improvement the specifications, details and dimensions shown in this publication are subject to change without notice FARA089d Page 1 of 2 Feb-00 (B) The SE121-00 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 75 Ω 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)
- 75 Ω output termination resistors provided
- Flat passband response - ADV encoder incorporates sin x/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 FILTER SPECIFICATION FOR EACH CHANNEL End of Passband 5.5 MHz Passband shape flat Sampling frequency - Amplitude ripple ± 0.1 dB to 5.5 MHz, ± 0.2 dB to 6 MHz Gain 0 dB ± 0.2 dB Group Delay ripple < 10 ns to 5.5 MHz Start of stopband 21 MHz Stopband rejection wrt 100 kHz > 30 dB Input impedance 100 k Ω typical Output impedance 75 Ω Supply voltage ± 5V Supply current 25 mA per rail (typical) Aqueous Washable Yes SE121-00 4-CHANNEL OVERSAMPLED POST FILTER
