As part of continual product improvement the specifications, details and dimensions shown in this publication are subject to change without notice FARA091d Page 1 of 2 Feb-00 (B) The SE131-00 is a single-in-line two channel active hybrid module designed to provide true broadcast quality filtering and buffering for the Fairchild/Raytheon TMC2490 encoder. Based on the popular Faraday AH1000 single channel filter the SE131-00 also compensates for the DC offset of the encoder output and provides a composite output by combining Y/C signals. Other features
- 2 independent filtered channels for oversampled PAL/NTSC Composite or Y/C
- accurate factory set gain of 0 dB
- 75 Ω input and output impedance
- sin x/x correction for 27 MHz sampling
- DC coupling eliminates tilt problems associated with AC coupling
- Drives two composite outputs and one Y/C output
- DC offset of encoder output ( due to single rail operation ) is corrected to bring blanking level near zero
- 14-pin SIL surface mount j-lead package FILTER SPECIFICATION FOR EACH CHANNEL End of Passband 5.75 MHz Passband shape sin x/x Sampling frequency 27 MHz Amplitude ripple 1 < 0.2 dB to 5.75 MHz, Gain 0 dB ± 0.2 dB Group Delay ripple 10 ns max to 5.75 MHz Start of stopband 21.5 MHz Stopband rejection wrt 100 kHz 40 dB min Input/Output impedance 75 Ω Supply voltage ± 5V Supply current 8 mA per rail (typical) Aqueous Washable Yes 1 measured against sin x/x predistortion curve SE131-00 VIDEO ENCODER POST FILTER
