SI5338A-B05317-GM

Overview

The SI5338A-B05317-GM is an I2C-programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency on four independent outputs with zero ppm precision and typical phase jitter of 0.7 ps RMS. The device supports differential inputs up to 710 MHz and single-ended inputs up to 350 MHz. Outputs include LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats. It operates from a single core supply of 1.8 V, 2.5 V, or 3.3 V within a 4x4 mm QFN-24 package.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers with 0 ppm accuracy.
• Low phase jitter of 0.7 ps RMS typical for high-speed serial applications like PCIe Gen 3/4.
• Flexible input reference options including external crystals (8–30 MHz), CMOS, SSTL/HSTL, and differential signals up to 710 MHz.
• Independent output voltage configuration per driver at 1.5, 1.8, 2.5, or 3.3 V.

Applications

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

Procurement Notes

Verify the specific ordering suffix B05317 against the manufacturer's current documentation to confirm the programmed frequency plan and output configurations. Ensure compatibility with the I2C/SMBus interface requirements and check for moisture sensitivity handling instructions during assembly.

Selection Notes

Select this component when low jitter (<1 ps RMS) and flexible output format support are required. Confirm that the desired output frequencies fall within the supported ranges for the chosen signal format (e.g., LVDS up to 710 MHz, CMOS up to 200 MHz). Verify power supply constraints match the available 1.8 V, 2.5 V, or 3.3 V rails.

Part Context

This part belongs to the Si5338 family of programmable clock generators. It replaces multiple discrete crystal oscillators by providing four independent clock outputs from a single reference source. The device integrates NVM programming capabilities for standalone operation after initial configuration.

Replacement Considerations

Direct pin-to-pin replacements within the same family require matching the output frequency plan and jitter specifications. Verify that alternative SKUs support the same output formats and voltage levels. Consult the official substitution guide for confirmed compatible parts.
