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
2
C/
SMBus-compatible serial interface and supports operation from a 1.8, 2.5, or
3.3 V core supply. I
2
C device programming is made easy with the ClockBuilder™
Desktop software available at
www.silabs.com/ClockBuilder.
Measuring PCIe
clock jitter is quick and easy with the Silicon Labs PCIe Clock Jitter Tool.
