SI5338M-B06630-GM

The Skyworks Solutions SI5338M-B06630-GM is a high-performance, low-jitter clock generator designed for flexible frequency synthesis. Utilizing patented MultiSynth™ technology, it can generate four independent clocks with 0 ppm precision, capable of replacing multiple crystal oscillators or acting as a frequency translator.

Each of the four output drivers is independently configurable to support various signal formats including LVPECL/LVDS, HCSL, CMOS, and SSTL/HSTL, with output frequencies ranging from 0.16 MHz up to 710 MHz depending on the format. The device supports a wide range of input references, from external crystals (8-30 MHz) to differential inputs (5-710 MHz).

Programmable via an I2C/SMBus-compatible serial interface, the Si5338 operates from a 1.8, 2.5, or 3.3 V core supply. It features independent output voltage configuration per driver (1.5, 1.8, 2.5, or 3.3 V), independent phase adjustment, and configurable spread spectrum clocking. The device is housed in a compact 4 x 4 mm QFN package, making it suitable for space-constrained applications.

Key features include low phase jitter of 0.7 ps RMS typical, high precision synthesis for zero ppm accuracy, and support for PCIe Gen 1/2/3/4 common clock and Gen 3 SRNS compliance. Applications include Ethernet switches, routers, and PCIe interfaces.
