SI5334K-B04338-GMR

Overview

The SI5334K-B04338-GMR is a pin-controlled, any-frequency quad clock generator from Skyworks Solutions. It synthesizes four differential output clocks 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 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. 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 zero ppm error.
• Low Jitter Performance: Typical RMS phase jitter of 0.7 ps for GbE and OC-12 applications.
• Flexible Output Drivers: Independently configurable signal formats (LVPECL, LVDS, HCSL, CMOS, etc.) and supply voltages per driver.
• PCI Express Compliance: Supports PCI Express 2.0 compliant spread spectrum modulation on 100 MHz outputs.

Applications

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

Procurement Notes

Verify the specific factory-programmed frequency plan associated with the B04338 suffix against the official Skyworks documentation. Confirm that the required output formats and supply voltages match the fixed configuration provided by this part number. Check current availability status as distribution may vary.

Selection Notes

Select this component when pin control is preferred over I2C interfaces. Ensure the design requires the specific frequency plan programmed into the NVM. Verify that the target application frequencies fall within the supported ranges (up to 350 MHz standard, up to 710 MHz for select frequencies). Confirm compatibility with the available output driver formats.

Part Context

This part belongs to the Si5334 family of pin-controlled clock generators. The 'K' suffix indicates support for PCI Express compliant spread spectrum. The 'B04338' suffix denotes a specific factory-programmed frequency plan stored in non-volatile memory. The 'GMR' suffix indicates tape and reel packaging.

Replacement Considerations

Direct replacements must be from the Si5334 family with identical pinouts and package dimensions. Verify that alternative part numbers have the same factory-programmed frequency plan or can be reconfigured if field-programmable options are available. Ensure electrical parameters like jitter and supply voltages remain compatible.
