SI5334M-B05322-GM

Overview

The SI5334M-B05322-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 low phase jitter (0.7 ps RMS typ). 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 individual supply voltages of 1.5, 1.8, 2.5, or 3.3 V. It features spread spectrum capabilities compliant with PCI Express.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with 0 ppm accuracy.
• Low phase jitter performance: 0.7 ps RMS typical.
• Flexible input reference options: external crystal (8-30 MHz), CMOS (up to 200 MHz), SSTL/HSTL (up to 350 MHz), or differential (up to 710 MHz).
• Independent output voltage per driver (1.5, 1.8, 2.5, or 3.3 V) and core supply (1.8, 2.5, or 3.3 V).

Applications

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

Procurement Notes

Verify the specific suffix 'M' indicates the inclusion of Spread Spectrum functionality compliant with PCI Express standards. Confirm that the factory-programmed configuration matches the required output frequencies and signal formats for the target application before procurement.

Selection Notes

Select this model if PCI Express compliant spread spectrum is required. Ensure the design accommodates the 24-QFN package dimensions and thermal requirements. Verify that the input reference source meets the electrical specifications for the chosen input type (crystal vs. clock).

Part Context

This component belongs to the Si5334 family of pin-controlled clock generators. The 'M' suffix in the part number distinguishes it from other variants by enabling spread spectrum modulation on outputs operating at 100 MHz. It shares the same physical footprint and general architecture as other Si5334 models but differs in internal programming.

Replacement Considerations

Direct replacements within the Si5334 family require matching the output frequency plan and signal format. Models without the 'M' suffix lack spread spectrum support. Cross-family replacements must be evaluated for pin compatibility and jitter performance.
