Overview
The SI5338A-B-GM is a high-performance, low-jitter clock generator produced by Skyworks Solutions Inc., although it is often associated with Silicon Labs due to the acquisition and integration of their technologies. This timing IC is capable of synthesizing any frequency on each of its four output drivers, making it a versatile replacement for multiple crystal oscillators and fixed-frequency clock generators. Using patented MultiSynth™ technology, the SI5338A-B-GM can generate four independent clocks with zero ppm frequency accuracy. Each output clock is independently configurable to support various signal formats and supply voltages, and the device is programmable via an I²C/SMBus-compatible serial interface.
