SI5338A-B05495-GM

Overview

The SI5338A-B05495-GM is a programmable clock generator utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended outputs with frequencies up to 710 MHz. The device operates from a core supply of 1.8, 2.5, or 3.3 V and features low phase jitter of 0.7 ps RMS typical. It accepts various input references including external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz). Configuration is performed via an I2C/SMBus interface.
