SI5334K-B04797-GM

Overview

The SI5334K-B04797-GM is a pin-controlled, low-jitter 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 accepts external crystals (8–30 MHz) or reference clocks (5–710 MHz). Key electrical parameters include a typical core supply current of 45 mA at 100 MHz operation, a typical RMS phase jitter of 0.7 ps, and an operating temperature range of –40 to +85 °C. It features independent output voltage configurations and supports spread spectrum for EMI reduction.

Feature Summary

• MultiSynth Technology: Enables zero ppm frequency error and low jitter synthesis on four differential outputs.
• Flexible Input/Output: Accepts inputs from 5 to 710 MHz; outputs support LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats.
• Pin-Controlled Operation: Factory-programmed configuration with no I2C interface required.
• Spread Spectrum Support: Includes PCI Express 2.0 compliant spread spectrum capability for EMI reduction.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm factory-programmed frequency plans and package variations. Confirm availability status as distribution channels may report limited stock or end-of-life conditions for specific pre-configured variants.

Selection Notes

Select this component when pin control is preferred over digital interfaces like I2C. Ensure the required output frequencies fall within the 350 MHz general limit or the 710 MHz selective limit. Verify that the target application supports the available output driver formats such as LVDS or LVPECL.

Part Context

This part belongs to the Si5334 family of quad clock generators. The 'K' suffix in the model number indicates specific feature sets, such as spread spectrum capabilities, distinguishing it from other variants in the series that may offer phase adjustment or different input/output configurations.

Replacement Considerations

Direct replacements within the same family require matching the pin count and package type. Verify if alternative models provide necessary features like spread spectrum or specific frequency ranges. Cross-model compatibility depends on identical factory programming requirements.

FAQ

Does the SI5334K support I2C programming?

No, the Si5334 is a pin-controlled device. Configuration is handled via factory programming into non-volatile memory rather than a digital interface.

What is the maximum output frequency supported?

The device supports any frequency up to 350 MHz on all outputs. Select frequencies can reach up to 710 MHz depending on the specific configuration.

How is spread spectrum implemented?

The Si5334K supports PCI Express 2.0 compliant spread spectrum on output clocks operating at 100 MHz to assist with EMI reduction.
