SI5334M-B09995-GM

Overview

The SI5334M-B09995-GM is a pin-controlled quad clock generator from Skyworks Solutions. It synthesizes any frequency on four differential outputs using MultiSynth technology, achieving zero ppm frequency error and 0.7 ps RMS typical jitter. The device supports flexible input references including crystals (8–30 MHz) and clocks up to 710 MHz. Outputs are independently configurable for formats such as LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL with independent supply voltages. This specific variant includes spread spectrum capabilities controlled via pins.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers.
• Low phase jitter of 0.7 ps RMS typical with true 0 ppm frequency accuracy.
• Flexible input reference options: external crystal (8-30 MHz), CMOS (5-200 MHz), or differential clock (up to 710 MHz).
• Pin-controlled spread spectrum feature compliant with PCI Express standards.

Applications

• Ethernet switch/router
• PCI Express 2.0/3.0
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the exact factory-programmed frequency plan associated with the B09995 suffix against the official Skyworks documentation. Confirm that the pin-controlled spread spectrum configuration matches system requirements. Ensure compatibility with the specified core supply voltage range of 1.8 V, 2.5 V, or 3.3 V during procurement validation.

Selection Notes

Select this component when low jitter and precise frequency synthesis are required without I2C programming overhead. The pin-controlled interface simplifies board design by eliminating serial communication lines. Verify that the required output frequencies fall within the supported ranges for the chosen signal format, noting that select frequencies can reach up to 710 MHz while others are limited to lower maximums.

Part Context

This part belongs to the Si5334 family of pin-controlled clock generators. The 'M' suffix indicates the inclusion of pin-controlled spread spectrum functionality. The 'GMR' suffix denotes the tape-and-reel packaging format suitable for automated surface-mount assembly in a 24-lead QFN package.

Replacement Considerations

Direct replacements within the Si5334 family include variants with different suffixes (e.g., C, K) depending on whether spread spectrum or specific frequency plans are needed. Ensure the substitute part supports the same pin control logic and output driver configurations if replacing in an existing design.
