SE121-00

The SE121-00 is designed as one kind of surface mountable four channel video output filter device that provides all the filtering and buffering requirements for the Analog Devices ADV7170 and ADV7171 encoders. And this device also gives minimal differential gain and phase distortion with the capability of driving up to ±2.5V into 75 loads.

Features of the SE121-00 are:(1)4 independent filtered channels for RGB and Alpha or dual S-video and dual composite.; (2)accurate factory set gain of 0 dB (6 dB optional - order SE121-60); (3)75 output termination resistors provided; (4)Flat passband response - ADV encoder incorporates sinx/x correction; (5)high input impedance - makes interfacing easy; (6)DC coupling eliminates tilt problems associated with AC coupling; (7)DC offset of encoder output (due to single rail operation) is corrected to bring blanking level near zero; (8)24-pin surface mount DIL package.

The absolute maximum ratings of the SE121-00 can be summarized as:(1)End of Passband 5.5 MHz; (2)Passband shape flat; (3)Sampling frequency -; (4)Amplitude ripple ± 0.1 dB to 5.5 MHz, ± 0.2 dB to 6 MHz; (5)Gain 0 dB ± 0.2 dB; (6)Group Delay ripple < 10 ns to 5.5 MHz; (7)Start of stopband 21 MHz; (8)Stopband rejection wrt 100 kHz > 30 dB; (9)Input impedance 100 k typical; (10)Output impedance 75; (11)Supply voltage ± 5V; (12)Supply current 25 mA per rail (typical); (13)Aqueous Washable Yes; (14)Package DR00134B.
