SI5338A-B04407-GM

Overview

The SI5338A-B04407-GM is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency with 0 ppm precision on four independent outputs, supporting 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 and accepts differential inputs up to 710 MHz. Key electrical parameters include a typical phase jitter of 0.7 ps RMS, a maximum output frequency of 710 MHz for differential signals, and an operating temperature range of -40 °C to +85 °C.

Feature Summary

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet revision to confirm pinout compatibility and factory programming settings. Confirm that the required I2C pull-up voltages align with the system design, as the device supports bus voltages from 1.71 V to 3.63 V.

Selection Notes

Select this component when zero-ppm frequency accuracy is required across multiple independent clocks. Ensure the target output voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) match the load requirements. Verify input signal integrity, maintaining slew rates above 0.3 V/ns for differential inputs to achieve optimal jitter performance.
