SI5338P-B04725-GMR

Application Specific Clock/Timing Overview

The SI5338P-B04725-GMR is a programmable quad clock generator from Skyworks Solutions. It utilizes MultiSynth technology to synthesize any frequency on four independent output drivers with zero ppm precision. The device supports differential and single-ended outputs, including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats. It operates from a single core supply of 1.8 V, 2.5 V, or 3.3 V and features low phase jitter of 0.7 ps RMS typical. Configuration is performed via an I2C/SMBus interface.

Application Specific Clock/Timing Feature Summary

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