SI5347B-B05059-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5347B-B05059-GM is a jitter-attenuating clock multiplier from Skyworks Solutions, integrating four independent DSPLLs. It supports any-frequency conversion with an ultra-low jitter performance of 95 fs rms (12 kHz to 20 MHz). The device accepts differential inputs from 8 kHz to 750 MHz and LVCMOS inputs up to 250 MHz. Outputs are configurable for differential frequencies up to 720 MHz or LVCMOS up to 250 MHz. It operates on a 1.8 V core voltage and includes in-circuit programmable non-volatile memory. The component is housed in a 64-QFN package.
