faraday Data Sheet TECHNOLOGY SE121-00 4-CHANNEL OVERSAMPLED POST FILTER The SE121-00 is a surface mountable four channel video output filter designed to provide all the filtering and buffering requirements for the Analog Devices ADV7170 and ADV7171 encoders. Use of high performance video operational amplifiers gives minimal differential gain and phase distortion with the capability of driving up to ± 2.5V into 75Ω loads. ! 4 independent filtered channels for RGB and Alpha or dual S-video and dual composite. ! accurate factory set gain of 0 dB (6 dB optional - order SE121-60) ! 75Ω output termination resistors provided ! Flat passband response - ADV encoder incorporates sinx/x correction ! 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 FILTER SPECIFICATION FOR EACH CHANNEL End of Passband Passband shape Sampling frequency Amplitude ripple Gain Group Delay ripple Start of stopband Stopband rejection wrt 100 kHz Input impedance Output impedance Supply voltage Supply current Package 5.5 MHz flat ± 0.1 dB to 5.5 MHz, ± 0.2 dB to 6 MHz 0 dB ± 0.2 dB < 10 ns to 5.5 MHz 21 MHz > 30 dB 100 kΩ typical 75Ω ± 5V 25 mA per rail (typical) DR00134B As part of continual product improvement the specifications, details and dimensions shown in this publication are subject to change without notice FARA089 Page 1 of 2 Mar-99(A) PACKAGE DETAIL Faraday Technology Ltd.
