SE131-00

The SE131-00 is designed as one kind of single-in-line two channel active hybrid device that provides true broadcast quality filtering and buffering for the Fairchild/Raytheon TMC2490 encoder. And this device also compensates for the DC offset of the encoder output and provides a composite output by combining Y/C signals.

Features of the SE131-00 are:(1)2 independent filtered channels for oversampled PAL/NTSC Composite or Y/C; (2)accurate factory set gain of 0 dB; (3)75 input and output impedance; (4)sinx/x correction for 27 MHz sampling; (5)DC coupling eliminates tilt problems associated with AC coupling; (6)Drives two composite outputs and one Y/C output; (7)DC offset of encoder output (due to single rail operation) is corrected to bring blanking level near zero; (8)14-pin SIL surface mount j-lead package.

The absolute maximum ratings of the SE131-00 can be summarized as:(1)End of Passband: 5.75 MHz; (2)Passband shape: sinx/x; (3)Sampling frequency: 27 MHz; (4)Amplitude ripple: < 0.2 dB to 5.75 MHz,; (5)Gain: 0 dB ± 0.2 dB; (6)Group Delay ripple: 10 ns max to 5.75 MHz; (7)Start of stopband: 21.5 MHz; (8)Stopband rejection wrt 100 kHz: 40 dB min; (9)Input/Output impedance: 75; (10)Supply voltage: ± 5V; (11)Supply current: 8 mA per rail (typical); (12)Aqueous Washable: Yes; (13)Package: DR00152A.
