SI5334M-B04511-GM

Overview

The SI5334M-B04511-GM 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). Each output driver is independently configurable for signal format and voltage (1.5, 1.8, 2.5, or 3.3 V). The core supply operates at 1.8, 2.5, or 3.3 V with a typical current of 45 mA. Configuration is stored in factory-programmed NVM.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential outputs with 0.7 ps RMS typical jitter.
• Flexible input support for external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential clocks (5–710 MHz).
• Pin-controlled frequency increment/decrement feature allows glitchless adjustments in 1 ppm steps.
• Highly-configurable output drivers support LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats with independent supply voltages.

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 ordering suffix against the manufacturer's official documentation to confirm the exact frequency plan and configuration parameters. Factory programming defines the operational settings; ensure the selected part number matches the required design specifications before procurement.

Selection Notes

Select this component when pin control is preferred over I2C interfaces. Ensure the application requires independent output voltage levels or specific signal formats like LVDS or HCSL. Verify that the input reference source falls within the supported frequency ranges for the desired output configurations.

Part Context

This part belongs to the Si5334 family of pin-controlled clock generators. The 'M' suffix indicates support for spread spectrum capabilities compliant with PCI Express standards. The device is packaged in a 24-lead QFN (4x4 mm) suitable for space-constrained designs.

Replacement Considerations

Consult Skyworks Solutions for custom versions or alternative part numbers within the Si5334 series that match specific frequency requirements. Direct substitutes may require verification of pin compatibility and electrical characteristics.
