SI5338N-B06173-GM

Overview

The SI5338N-B06173-GM is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers with zero ppm precision. It supports differential and single-ended outputs including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. The device operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, with individual output supplies configurable from 1.5 V to 3.3 V. It features low phase jitter of 0.7 ps RMS typical, flexible input references up to 710 MHz, and I2C/SMBus programming.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm pinout, package type, and factory configuration. Ensure compatibility with the intended I2C bus voltage levels, as the device supports standard mode and fast mode operations across varying supply voltages.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single IC. Consider the output driver voltage requirements (1.5 V to 3.3 V) and signal format compatibility with the target receivers. Verify that the input reference source matches the supported frequency ranges for crystal, CMOS, or differential inputs.
