SI5350C-B01863-GT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5350C-B01863-GT is a factory-programmable CMOS clock generator featuring a dual PLL and MultiSynth fractional divider architecture. It generates up to eight non-integer-related frequencies ranging from 2.5 kHz to 200 MHz with 0 ppm error. The device supports independent core (VDD) and output buffer (VDDO) supply voltages of 1.8 V, 2.5 V, or 3.3 V. It accepts a 25 MHz or 27 MHz crystal reference or an external clock input between 10 MHz and 100 MHz. Typical period jitter is less than 70 ps peak-to-peak. The component operates within an ambient temperature range of -40 °C to 85 °C.
