SE110-00

SE110-00 SET-TOP VIDEO POST FILTER The SE110-00 is a surface mountable active hybrid module designed to interface Philips SAA7185 series digital video encoders to 75Ω composite (CMPS), Luma (Y) and Chroma (C) outputs. Use of high performance operational amplifiers ensures minimal differential phase/gain errors and the ability to drive ± 2.5V into 75Ω loads. Other features ! Drives two composite outputs and one Y/C output ! accurate factory set gain of 0 dB (6 dB optional - order SE110-60) ! 75Ω output termination resistors provided ! sinx/x correction for 27 MHz sampling ! 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 j-lead surface mount package FILTER SPECIFICATION FOR EACH CHANNEL End of Passband 6.0 MHz Passband shape sinx/x Sampling frequency Amplitude ripple1 27 MHz ± 0.5 dB to 6.0 MHz, Gain 0 dB ± 0.2 dB Group Delay ripple < 10 ns Start of stopband 21 MHz Stopband rejection wrt 100 kHz > 40 dB (with sinx/x) Input impedance 100 kΩ typical Output impedance 75Ω Supply voltage ± 5V Supply current 25 mA per rail (typical) Package 1 measured against sinx/x predistortion curve DR00144A © Faraday Technology.
