SE131-00 VIDEO ENCODER POST FILTER 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 • 75Ω input and output impedance • sinx/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 sinx/x Sampling frequency 27 MHz 1 Amplitude ripple < 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 75Ω Supply voltage ± 5V Supply current 8 mA per rail (typical) Aqueous Washable Yes Package DR00152A 1 measured against sinx/x predistortion curve © Faraday Technology.
