SI5334C-B04813-GMR

Overview

The SI5334C-B04813-GMR 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 phase jitter. The device supports flexible input references including crystals (8–30 MHz) and clocks up to 710 MHz. Outputs are independently configurable for formats such as LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL with independent supply voltages of 1.5, 1.8, 2.5, or 3.3 V. It operates on a core supply of 1.8, 2.5, or 3.3 V within the -40 to +85 °C range.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with 0.7 ps RMS typical jitter.
• Flexible input reference options: external crystal (8-30 MHz), CMOS (5-200 MHz), SSTL/HSTL (5-350 MHz), or differential (5-710 MHz).
• Highly-configurable output drivers support LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats with independent voltage selection.
• Pin-controlled configuration without I2C interface; factory-programmable NVM ensures operation upon power-up.

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 frequency plan associated with the B04813 suffix against the official Skyworks datasheet, as this code defines the programmed output frequencies. Confirm package type is 24-QFN and check RoHS compliance status. Ensure the required input reference matches the device's supported ranges.

Selection Notes

Select this model when pin control is preferred over I2C programming. Verify that the target output frequencies fall within the 0.16 MHz to 350 MHz standard range or the select frequencies up to 710 MHz. Ensure the application requires independent output voltage levels compatible with the 1.5V to 3.3V driver supplies.

Part Context

This component belongs to the Si5334 family of pin-controlled clock generators. The 'C' suffix typically denotes a specific feature set or revision within the series, while 'GMR' indicates tape-and-reel packaging. It is designed for high-performance clock distribution in datacom and telecom infrastructure.

Replacement Considerations

Direct replacements must be verified by matching the exact frequency plan encoded in the ordering suffix. Other Si5334 variants may differ in features like spread spectrum capability or phase adjustment functions. Consult the manufacturer for cross-reference availability.
