SI5338H-A-GM

Overview

The SI5338H-A-GM is a programmable quad clock generator from Skyworks Solutions, 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 on a single core supply of 1.8 V, 2.5 V, or 3.3 V and features independently configurable output voltages (1.5 V, 1.8 V, 2.5 V, or 3.3 V). Key electrical parameters include a typical RMS jitter of 0.7 ps, a maximum input frequency of 710 MHz, and a maximum output frequency of 710 MHz for LVPECL/LVDS/CML formats. It is housed in a 4x4 mm QFN-24 package.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four output drivers with 0 ppm precision.
• Supports PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliance.
• Flexible output drivers support LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats.
• Low phase jitter of 0.7 ps RMS typical.

Applications

• PCIe Gen1/2/3/4
• Ethernet switch/router
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific ordering suffix 'H' against the manufacturer's official documentation to confirm pinout, packaging, or functional variations compared to standard variants. Ensure compatibility with I2C/SMBus programming interfaces and required supply voltage levels during procurement planning.

Selection Notes

Select this component when low-jitter, flexible frequency synthesis is required for high-speed serial interfaces like PCIe. Consider the available output formats (LVPECL, LVDS, etc.) and supply voltage requirements (1.8 V, 2.5 V, 3.3 V) to match the target system design. Use ClockBuilder Pro software for configuration.

Part Context

The SI5338H-A-GM belongs to the Si5338 family of I2C-programmable clock generators. This series is designed to replace multiple crystal oscillators by providing four independent clock outputs with high precision and low jitter in a compact QFN package.

Replacement Considerations

Consult the official datasheet for confirmed substitute part numbers within the Si5338 family. Verify pin compatibility and electrical specifications before substituting with other models.
