Description
The SKY73201-364LF & SKY73202-364LF are high-performance, programmable, monolithic, clock-referenced low-pass filters. They are configured as a 6th order Butterworth to provide extremely high stop-band isolation while maximizing pass-band flatness and minimizing group delay distortion. The corner frequency is programmable, via the 3-wire Serial Peripheral Interface (SPI), in steps, from 1–28 MHz, when a 20 MHz or 40 MHz reference is used.
