RFR1772S

The RFR1772S is designed as one kind of antialiasing filter device that is 40 pin DIL suitable for direct mounting in a pcb. Ground pins should be taken to separate earth points to maintain transmission line characteristics if the full stopband performance is required.

The electrical characteristics of the RFR1772S can be summarized as:(1)Filter Shape: Lowpass;(2)Passband Shape: Sinx/x;(3)Sampling Frequency: 17.72 MHz;(4)Attenuation at S.F. wrt 100 kHz: > 70 dB;(5)Insertion Loss at 100 kHz: < 2.5 dB;(6)End Of Passband: 5.5 MHz;(7)Passband Ripple wrt 100 kHz: +/- 0.15 dB;(8)Loss at half S.F. wrt 100 kHz: 16.5 dB;(9)Start Of Stopband: 11.75 MHz;(10)Stopband Attenuation: > 50 dB;(11)Group Delay Ripple wrt 200 kHz: +/- 5.0 ns;(12)Group Delay Bandwidth: 5.0 MHz;(13)Delay Time at 200 kHz: 240 ns nom.
