SI5338A-B07234-GM

Overview

The SI5338A-B07234-GM is a programmable clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports input frequencies up to 710 MHz and generates outputs with 0 ppm precision. The device operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, with typical current consumption of 45 mA. It features low phase jitter of 0.7 ps RMS typ and supports various output formats including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. Packaged in a 24-lead QFN (4x4 mm), it functions within an ambient temperature range of -40 °C to +85 °C.
