SI5345B-B00003-GM

Clock Generators, PLLs, Frequency Synthesizers Overview

The Skyworks SI5345B-B00003-GM is a low-jitter, 10-output clock synthesizer and jitter attenuator. It supports any-frequency generation up to 350 MHz with ultra-low jitter of 90 fs rms. The device features four inputs (differential: 8 kHz–750 MHz; LVCMOS: 8 kHz–250 MHz) and ten configurable outputs supporting LVDS, LVPECL, LVCMOS, CML, and HCSL formats. Operating voltage ranges from 1.71 V to 3.47 V, with a maximum power dissipation of 880 mW. It operates within a temperature range of -40°C to +85°C in a QFN-64 package.
