SI5334M-B04510-GM

Overview

The SI5334M-B04510-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 input frequencies up to 710 MHz and output frequencies up to 350 MHz (selectively to 710 MHz). It features independent output voltage configurations (1.5V to 3.3V) and core supply options (1.8V, 2.5V, or 3.3V). Key capabilities include glitchless frequency increment/decrement in 1 ppm steps, phase adjustment with <20 ps resolution, and PCI Express compliant spread spectrum modulation.

Feature Summary

• MultiSynth Technology: Enables independent, any-frequency synthesis on four differential outputs with 0 ppm accuracy and low jitter.
• Flexible Input/Output: Accepts crystal (8-30 MHz) or clock inputs (up to 710 MHz); outputs support LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats.
• Glitchless Frequency Adjustment: Pin-controlled frequency increment/decrement feature allows adjustments in 1 ppm steps without glitches.
• Spread Spectrum: Supports PCI Express compliant spread spectrum modulation for EMI reduction.

Applications

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

Procurement Notes

Verify the specific suffix 'M' against the datasheet's ordering information table to confirm it corresponds to the variant with pin-controlled frequency increment/decrement capabilities. Ensure the factory-programmed frequency plan matches the target application requirements, as the configuration is fixed upon manufacturing.

Selection Notes

Select this component when pin control is preferred over I2C programming. Verify that the required output signal formats (LVPECL, LVDS, etc.) and voltage levels are supported by the independent VDDOx supplies. Confirm that the input reference source (crystal vs. external clock) aligns with the device's input stage capabilities.

Part Context

This part belongs to the Si5334 family of pin-controlled clock generators. The 'M' suffix typically denotes a specific feature set within the family, such as the inclusion of frequency increment/decrement functionality, distinguishing it from variants like 'C' or 'K'.

Replacement Considerations

Direct replacements must be sought from the Si5334 family. Verify if other suffixes (e.g., C, K, J) offer compatible pinouts and electrical characteristics. Note that different suffixes may lack specific features like frequency stepping or spread spectrum.
