OVERSAMPLED POST FILTER

SE120-00

4-CHANNEL

The AH1145 is a surface mountable four channel oversampled post filter designed to provide all the filtering and buffering requirements for the Fairchild/Raytheon TMC2192/93 encoder.  Use of high performance video operational amplifiers gives minimal  differential gain and phase distortion with the capability of driving up to ± 2.5V into 75W 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

• ·      75W output termination resistors provided

• ·      sinx/x correction for 27 MHz sampling plus compensation for the encoder roll-off

• ·      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
