Description

The Si5338 is a high-performance, low-jitter clock generator capable of

synthesizing any frequency on each of the device's four output drivers. This timing

IC is capable of replacing up to four different frequency crystal oscillators or

operating as a frequency translator. Using its patented MultiSynth™ technology,

the Si5338 allows generation of four independent clocks with 0 ppm precision.

Each output clock is independently configurable to support various signal formats

and supply voltages. The Si5338 provides low-jitter frequency synthesis in a

space-saving 4 x 4 mm QFN package. The device is programmable via an I

SMBus-compatible serial interface and supports operation from a 1.8, 2.5, or

3.3 V core supply. I
