SE130-00 - Faraday Technology

SE130-00
VIDEO ENCODER POST FILTER
The SE130-00 is a surface mountable 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 SE130-00 also compensates for the DC offset of the
encoder output and provides a composite output by combining Y/C signals.
! 2 independent filtered channels for oversampled PAL/NTSC Composite or Y/C
! accurate factory set gain of 0 dB or 6 dB (order SE130-60)
! 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
! 24-pin DIL surface mount j-lead package
