SI5338C-B05004-GMR

Overview

The SI5338C-B05004-GMR is a programmable quad clock generator utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended 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 with individual output voltages configurable between 1.5 V and 3.3 V. Key electrical parameters include a maximum input frequency of 710 MHz, typical phase jitter of 0.7 ps RMS, and an operating temperature range of –40 °C to +85 °C.

Feature Summary

• MultiSynth™ technology enables zero ppm precision synthesis on four independent outputs.
• Supports flexible input references: external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz).
