6th Order Programmable Low Pass Butterworth Filter

The SKY73201-364LF is a high performance, programmable, monolithic, clock-referenced low pass filter. It is configured as a 6th order Butterworth to provide extremely high stop-band isolation while maximizing pass-band flatness and minimizing group delay distortion. The SKY73201-364LF is programmable in 1 MHz steps, from 128 MHz, via the 3-wire Serial Port Interface (SPI). Nearly ideal Butterworth performance is maintained over process variations via a proprietary internal calibration circuit which derives its timing accuracy from a 20 or 40 MHz reference clock.
