SI5380A-D07754-GMR

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5380A-D07754-GMR is a high-performance, integer-based jitter attenuator and clock multiplier designed for small cell applications. It utilizes 4th generation DSPLL technology to combine frequency synthesis and jitter attenuation in a digital solution, eliminating the need for external VCXO and loop filter components. The device features four inputs and twelve outputs within a 64-QFN package. Key electrical parameters include an ultra-low phase noise floor of -159 dBc/Hz and typical jitter performance of 65 fs (12 kHz to 20 MHz). Input frequencies range from 11.52 MHz to 737.28 MHz differentially, while output frequencies extend up to 1.47456 GHz differentially. Operating temperatures span from -40°C to +85°C.
