SI5338A-B10382-GM

Overview

The SI5338A-B10382-GM is an I2C-programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency on four independent output drivers with 0 ppm precision and a typical phase jitter of 0.7 ps RMS. The device supports differential inputs up to 710 MHz and single-ended inputs up to 200 MHz. Outputs are configurable for LVPECL, LVDS, CML, HCSL, CMOS, SSTL, or HSTL formats, supporting frequencies from 0.16 MHz to 710 MHz depending on the format. It operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V with a typical current of 45 mA.
