SI5338A-B01953-GM

The Skyworks Solutions SI5338A-B01953-GM is a high-performance, low-jitter clock generator designed for versatile timing applications. Utilizing patented MultiSynth™ technology, it can synthesize any frequency on each of its four independent output drivers with 0 ppm precision. This device is capable of replacing multiple crystal oscillators or acting as a frequency translator.

Key electrical specifications include a low phase jitter of 0.7 ps RMS typical. The device supports a wide range of input references, from external crystals (8-30 MHz) to differential inputs (5-710 MHz). Output frequencies can be configured independently for various formats like LVPECL/LVDS (0.16-710 MHz), HCSL (0.16-250 MHz), CMOS (0.16-200 MHz), and SSTL/HSTL (0.16-350 MHz). The core supply voltage operates from 1.8 to 3.3 V, with independent output voltage configuration per driver from 1.5 to 3.3 V.

This clock generator is compliant with PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS standards. It offers highly configurable output drivers, supporting up to four differential outputs, eight single-ended clock outputs, or a combination. The device operates over a wide temperature range of -40 to +85 °C and is housed in a compact 4x4 mm 24-QFN package, making it suitable for space-constrained designs. Programming is facilitated via an I2C/SMBus-compatible serial interface, with software support available through Skyworks' ClockBuilder Pro.

Applications include Ethernet switches and routers, and PCIe Gen1/2/3/4 systems. The device's flexibility in frequency synthesis, output formats, and voltage configurations makes it a robust solution for complex timing requirements.
