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. Nearly ideal Butterworth performance is maintained over temperature and process via a proprietary internal calibration circuit which derives its timing accuracy from the reference clock. Nominal reference clock frequencies of 20 MHz or 40 MHz are recommended to meet the specifications outlined in this data sheet but other reference clock frequencies can be accommodated with appropriate changes to the control register settings. The corner frequency range can be extended beyond 28 MHz by the use of alternate reference clock frequencies and modified control register settings.
