SI5338A-B01941-GM

The Skyworks Solutions SI5338A-B01941-GM is a high-performance, low-jitter clock generator capable of synthesizing any frequency on each of its four output drivers. Utilizing patented MultiSynth™ technology, it allows for the generation of four independent clocks with 0 ppm precision. Each output clock is independently configurable to support various signal formats and supply voltages, including LVPECL, LVDS, HCSL, CMOS, and SSTL/HSTL.

Key electrical specifications include a low phase jitter of 0.7 ps RMS typical and high precision synthesis for true zero ppm frequency accuracy. The device supports flexible input references ranging from external crystals (8-30 MHz) to differential inputs (5-710 MHz). Output frequencies can range from 0.16 MHz up to 710 MHz depending on the selected output format.

This clock generator operates from a 1.8, 2.5, or 3.3 V core supply and supports independent output voltages per driver from 1.5 to 3.3 V. It is programmable via an I2C/SMBus-compatible serial interface. The device also features configurable spread spectrum capabilities and independent phase adjustment on each output driver.

Packaged in a compact 4x4 mm 24-QFN, the SI5338A-B01941-GM is suitable for space-constrained designs. It operates across a wide temperature range of -40 to +85 °C, making it a versatile choice for applications such as Ethernet switches, routers, and PCIe Gen1/2/3/4 systems.
