SI5334M-B05322-GMR

Overview

The SI5334M-B05322-GMR is a pin-controlled clock generator from Skyworks Solutions, utilizing MultiSynth technology for independent frequency synthesis on four differential outputs. It supports any frequency up to 350 MHz and select frequencies up to 710 MHz with zero ppm error and 0.7 ps RMS typical jitter. The device accepts external crystals (8–30 MHz) or reference clocks (5–710 MHz). Key features include glitchless frequency increment/decrement in 1 ppm steps, phase adjustment (<20 ps steps), and PCI Express compliant spread spectrum. It operates on a 1.8 V, 2.5 V, or 3.3 V core supply within an industrial temperature range of –40 to +85 °C.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers.
• Glitchless frequency increment/decrement feature allows adjustments in 1 ppm steps.
• Supports Spread Spectrum Clocking (SSC) compliant with PCI Express standards.
• Phase adjustment capability on each output driver with <20 ps step accuracy.

Applications

• Ethernet switch/router
• PCI Express 2.0/3.0
• Processor and FPGA clocking
• Telecom line cards

Procurement Notes

Verify the specific suffix 'M' against the official datasheet to confirm the inclusion of Spread Spectrum functionality, as this variant differs from standard models. Ensure compatibility with the required input reference frequency and output signal formats before procurement.

Selection Notes

Select this model if pin-controlled configuration without I2C is required. Verify that the target application utilizes the glitchless frequency adjustment feature, which is specific to the M-series variants. Confirm that the output voltage levels (LVPECL, LVDS, HCSL, etc.) match the load requirements.

Part Context

This component belongs to the Si5334 family of pin-controlled quad clock generators. The 'M' suffix typically denotes support for Spread Spectrum Clocking (SSC) compliant with PCI Express specifications, distinguishing it from non-SSC variants like the A, B, or C series.

Replacement Considerations

Direct replacements must be verified by checking the ordering information table in the datasheet for identical electrical characteristics and package dimensions. Substituting with other Si5334 variants requires confirming whether the specific feature set (e.g., SSC support) is mandatory for the design.
