SI5334K-B04796-GMR

Overview

The SI5334K-B04796-GMR is a pin-controlled clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four differential outputs. It supports input frequencies up to 710 MHz and generates outputs with low jitter (0.7 ps RMS typ). The device allows independent configuration of output formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL, with supply voltages of 1.8 V, 2.5 V, or 3.3 V. It features spread spectrum capabilities compliant with PCI Express standards.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential outputs with zero ppm frequency error.
• Low phase jitter of 0.7 ps RMS typical.
• Supports flexible input references: external crystal (8-30 MHz), CMOS (5-200 MHz), SSTL/HSTL (5-350 MHz), or differential (5-710 MHz).
• Pin-controlled operation with factory-programmable NVM for immediate startup.

Applications

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

Procurement Notes

Verify the specific ordering suffix B04796 against the manufacturer's current documentation to confirm the exact frequency plan and output configurations. Check availability status as distribution may vary. Ensure compliance with RoHS requirements if applicable to the specific revision.

Selection Notes

Select this component when pin control is preferred over I2C interfaces. Ensure the required output frequencies fall within the supported ranges (up to 350 MHz generally, select frequencies up to 710 MHz). Verify that the power supply constraints (1.8V, 2.5V, or 3.3V core) match the system design.

Part Context

This part belongs to the Si5334 family of pin-controlled quad clock generators. The 'K' suffix typically indicates support for Spread Spectrum Clocking (SSC) compliant with PCI Express standards. The 'GMR' suffix denotes the tape and reel packaging format suitable for automated surface-mount assembly.

Replacement Considerations

Direct replacements within the same family include other Si5334 variants with different suffixes (e.g., Si5334A, Si5334B, Si5334C) which share the same package and basic functionality but may differ in specific frequency plans or feature sets like SSC. Consult the datasheet for cross-reference details.
