SI5334C-B04801-GMR

Overview

The SI5334C-B04801-GMR is a pin-controlled quad clock generator utilizing MultiSynth technology. It synthesizes any frequency on four differential outputs, supporting up to 350 MHz generally and select frequencies up to 710 MHz. The device features low phase jitter of 0.7 ps RMS typ and zero ppm frequency accuracy. It accepts external crystals (8–30 MHz) or input clocks (5–710 MHz). Each output driver supports independent voltage levels (1.5, 1.8, 2.5, or 3.3 V) and formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. Powered by a core supply of 1.8, 2.5, or 3.3 V, it operates within –40 to +85 °C in a 24-QFN package.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis with 0.7 ps RMS typical jitter.
• Four highly-configurable differential outputs support LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats.
• Flexible input reference options include external crystals (8–30 MHz) and differential/single-ended clocks (up to 710 MHz).
• Independent output buffer supply voltages allow mixed-voltage operation (1.5, 1.8, 2.5, or 3.3 V).

Applications

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

Procurement Notes

Verify the specific suffix 'B04801' against the manufacturer's current ordering guide to confirm factory-programmed frequency plans. Confirm RoHS compliance status and moisture sensitivity level requirements for the assembly process. Check for obsolescence notices as Skyworks may update product lines without notice.

Selection Notes

Select this model when pin control is preferred over I2C programming. Ensure the required output frequencies fall within the 350 MHz limit or verify if they match the specific select frequencies allowed up to 710 MHz. Validate that the target system supports the available output voltage levels and signal formats provided by the configurable drivers.

Part Context

This component belongs to the Si5334 family of pin-controlled clock generators from Skyworks Solutions. The 'C' variant typically denotes specific feature sets or output capabilities within the series. The '-GMR' suffix indicates tape and reel packaging suitable for automated surface-mount assembly.

Replacement Considerations

Direct replacements must be verified through Skyworks Solutions using the part number configuration tool. Cross-model substitution requires matching the pinout, package type (24-QFN), and electrical specifications precisely.
