SI5338M-B11132-GM

The Skyworks Solutions Si5338 is a high-performance, low-jitter clock generator designed for flexible frequency synthesis. It features patented MultiSynth™ technology, allowing for four independent clocks with 0 ppm precision. Each output can be configured for various signal formats and supply voltages, including LVPECL, LVDS, HCSL, CMOS, and SSTL/HSTL.

This device supports a wide range of input references, from external crystals (8-30 MHz) to differential inputs (5-710 MHz). The output frequencies can range from 0.16 MHz up to 710 MHz depending on the format. It operates from a 1.8, 2.5, or 3.3 V core supply and offers independent output voltage configuration per driver.

The Si5338 is programmable via an I2C/SMBus-compatible serial interface. It is housed in a compact 4x4 mm 24-QFN package, making it suitable for space-constrained applications. The device also supports configurable spread spectrum on any output and offers features like loss of lock and loss of signal alarms.

Key applications include Ethernet switches/routers, PCIe Gen1/2/3/4 systems, and general telecom infrastructure. The low phase jitter of 0.7 ps RMS typ and high precision synthesis make it ideal for demanding timing applications.
