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
