com preliminary data sheet SKY73201-364LF, SKY73202-364LF: Programmable 1–28 MHz 6th Order Low Pass Filters Applications H igh-performance direct conversion receivers • Software-defined radio basebands • High-definition television tuners • Medical imaging • Flexible anti-aliasing and reconstruction filters l 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.
Please contact Skyworks Solutions applications engineering for assistance with your requirements.
Additionally, the SKY73201-364LF & SKY73202-364LF offer excellent linearity and input noise level (83 dB SNR at 1 MHz corner setting), making them suitable for extremely high dynamic range applications such as adjacent channel rejection filters in direct conversion receivers.
The I/O interface is fully differential, but may also be used single-ended, and on-chip input/output drivers allow easy integration between modern system components such as mixers, data converters, and variable gain amplifiers.
