SI5338K-B10518-GM

Overview

The SI5338K-B10518-GM is a programmable quad 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, achieving typical phase jitter of 0.7 ps RMS. The device operates from a single core supply of 1.8 V, 2.5 V, or 3.3 V and features I2C/SMBus programming for flexible configuration.

Feature Summary

• Low phase jitter of 0.7 ps RMS typical
• Supports LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL output formats
• I2C/SMBus compatible interface for configuration

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant
• Ethernet switch/router
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape/reel specifications. Ensure compatibility with the required input reference frequencies and output voltage levels before procurement.

Selection Notes

Select this component when zero ppm frequency accuracy and low jitter are critical. Verify that the required output signal formats (LVPECL, LVDS, etc.) and frequencies fall within the supported ranges defined in the datasheet electrical specifications.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces multiple discrete crystal oscillators by providing four independently configurable clock outputs from a single IC, reducing board space and design complexity.

Replacement Considerations

Consult the official Skyworks Solutions cross-reference documentation for verified substitute part numbers. Do not assume functional equivalence with other series without verifying pinout and electrical parameter compatibility.
