SI5338N-B-GM

Overview

The SI5338N-B-GM is a programmable quad clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended outputs with formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. The device operates from a single core supply of 1.8 V, 2.5 V, or 3.3 V and accepts flexible input references up to 710 MHz. Key electrical parameters include a maximum output frequency of 710 MHz, typical phase jitter of 0.7 ps RMS, and a core supply current of 45 mA.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis with 0 ppm precision on four output drivers.
