SI5338B-B09602-GM

The Skyworks Solutions SI5338B-B09602-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 achieves 0 ppm precision for independent clock generation. This IC supports various signal formats and supply voltages, making it suitable for replacing multiple crystal oscillators or acting as a frequency translator.

The device operates from a 1.8, 2.5, or 3.3 V core supply and is programmable via an I2C/SMBus-compatible serial interface. It features highly configurable output drivers supporting formats like LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL, with independent output voltage configuration per driver. The SI5338B-B09602-GM provides low phase jitter of 0.7 ps RMS typical and true zero ppm frequency accuracy.

Designed for space-saving applications, it comes in a compact 4 x 4 mm QFN package. The wide operating temperature range of -40 to +85 °C makes it suitable for demanding environments. Applications include Ethernet switches/routers and PCIe Gen1/2/3/4 systems.

Key features include independent frequency synthesis on four differential output drivers, PCIe Gen1/2/3/4 compliance, and flexible input references ranging from external crystals to differential inputs up to 710 MHz. It also supports configurable spread spectrum on any output.
