The Skyworks Solutions SI5338A-B01942-GM is a high-performance, low-jitter clock generator. It utilizes patented MultiSynth™ technology to synthesize any frequency on each of its four output drivers, capable of replacing multiple crystal oscillators or acting as a frequency translator.
This device provides four independent clocks with 0 ppm precision. Each output is configurable for various signal formats and supply voltages, supporting frequencies from 0.16 MHz up to 710 MHz depending on the output format (LVPECL/LVDS, HCSL, CMOS, SSTL/HSTL). The core supply operates from 1.8, 2.5, or 3.3 V, with independent output voltages per driver selectable from 1.5, 1.8, 2.5, or 3.3 V.
Key features include low phase jitter of 0.7 ps RMS typical, configurable spread spectrum on any output, and independent phase adjustment. It is programmable via an I2C/SMBus-compatible serial interface. The device is housed in a compact 4 x 4 mm, 24-QFN package, making it suitable for space-constrained applications.
Applications include Ethernet switches/routers and PCIe Gen1/2/3/4 interfaces. The device operates over a wide temperature range of -40 to +85 °C.
