SI5334K-B04796-GM

Overview

The SI5334K-B04796-GM is a pin-controlled quad clock generator from Skyworks Solutions. It synthesizes any frequency on four differential outputs using MultiSynth technology, supporting frequencies up to 350 MHz generally and select frequencies up to 710 MHz. The device features low phase jitter of 0.7 ps RMS typical and zero ppm frequency accuracy. It accepts external crystals (8–30 MHz) or reference clocks (5–710 MHz). Each output supports independent voltage levels (1.5, 1.8, 2.5, or 3.3 V) and formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. The core supply operates at 1.8, 2.5, or 3.3 V.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential outputs with 0.7 ps RMS typical jitter.
• Supports PCI Express 2.0 compliant spread spectrum modulation for EMI reduction on 100 MHz outputs.
• Flexible input options include external crystals (8–30 MHz) and reference clocks (5–710 MHz).
• Independent output drivers support multiple signal formats (LVPECL, LVDS, HCSL, CMOS, SSTL, HSTL) with configurable supply voltages.

Applications

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

Procurement Notes

Verify the specific suffix 'K' indicates the inclusion of spread spectrum functionality as defined in the datasheet's ordering information section. Confirm that the factory-programmed frequency plan matches the target application requirements, as the device is configured via NVM upon power-up without user intervention.

Selection Notes

Select this model when PCI Express 2.0 compliant spread spectrum is required. Ensure the design accommodates the 24-lead QFN package dimensions. Verify that the required output frequencies fall within the supported ranges: up to 350 MHz for general use and up to 710 MHz for specific integer-related frequencies. Check compatibility with the available input reference sources.

Part Context

This component belongs to the Si5334 family of pin-controlled clock generators. The 'K' suffix distinguishes it from other variants by adding spread spectrum capabilities. It shares the same physical footprint and basic electrical characteristics with the Si5334A through Si5334J series, differing primarily in programmable features and output configurations.

Replacement Considerations

Direct replacements must be selected from the Si5334 family. Models such as SI5334C or SI5334D may serve as functional substitutes if spread spectrum is not required. Verify that the replacement part number supports the necessary output frequencies and signal formats.
