SI5334M-B05964-GMR

Overview

The SI5334M-B05964-GMR 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). Outputs are independently configurable for formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL with individual supply voltages of 1.5, 1.8, 2.5, or 3.3 V. The core operates at 1.8, 2.5, or 3.3 V in a 24-QFN package.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with zero ppm frequency error.
• Low phase jitter performance of 0.7 ps RMS typical across all outputs.
• Flexible input reference options including external crystals (8–30 MHz), CMOS (5–200 MHz), and differential inputs (5–710 MHz).
• Supports spread spectrum modulation compliant with PCI Express standards for EMI reduction.

Applications

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

Procurement Notes

Verify the specific factory-programmed frequency plan associated with the B05964 suffix against the system requirements before procurement. Confirm that the required output signal formats and voltage levels match the device's configuration capabilities. Ensure the design accommodates the 24-QFN package thermal characteristics and PCB land pattern recommendations provided in the datasheet.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single source with strict jitter constraints. Verify that the desired output frequencies fall within the supported ranges: up to 350 MHz for general use and up to 710 MHz for specific integer-related frequencies. Ensure the application supports pin-controlled configuration rather than I2C if dynamic changes are needed via pins.

Part Context

This part belongs to the Si5334 family of pin-controlled clock generators. The 'M' suffix indicates support for spread spectrum features compliant with PCI Express standards. The 'GMR' suffix denotes tape and reel packaging suitable for automated surface-mount assembly processes.

Replacement Considerations

Direct replacements must be selected from the Si5334 family with matching output count and package type. Verify that alternative parts support the same spread spectrum requirements if applicable. Cross-reference the specific frequency plan as it is unique to each ordering suffix.
