SI5334M-B04510-GMR

Overview

The SI5334M-B04510-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 jitter. Outputs support formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL with independent voltage selection (1.5V to 3.3V). The device accepts external crystals (8–30 MHz) or reference clocks (5–710 MHz). It features spread spectrum capabilities compliant with PCI Express standards for EMI reduction. Powered by a single core supply of 1.8V, 2.5V, or 3.3V, it operates within the -40°C to +85°C range in a 24-lead QFN package.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with 0.7 ps RMS typical phase jitter.
• Supports flexible input references: external crystal (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), or differential (5–710 MHz).
• Highly-configurable output drivers allow up to four differential or eight single-ended outputs with independent voltage levels (1.5V, 1.8V, 2.5V, or 3.3V).
• Pin-controlled configuration with factory-programmed NVM; includes spread spectrum compliance for PCI Express applications.

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 current documentation to confirm the exact frequency plan and pin control settings. Factory programming defines the operational parameters upon power-up. Confirm availability status directly with authorized distributors as stock levels fluctuate.

Selection Notes

Select this component when low jitter (<1 ps RMS) and precise frequency accuracy are required for high-speed digital interfaces. Ensure the target output frequencies fall within the supported ranges for the chosen signal format (e.g., LVDS up to 710 MHz, CMOS up to 200 MHz). Verify that the input reference source matches the device's compatible input types.

Part Context

This part belongs to the Si5334 family of pin-controlled clock generators. The 'M' suffix indicates specific internal configuration options, likely related to spread spectrum features or output driver characteristics compared to other variants like the Si5334C or Si5334K. All variants share the same 24-QFN footprint and core electrical specifications.

Replacement Considerations

Direct replacements must match the 24-QFN package and core supply requirements. Other Si5334 variants (e.g., Si5334C, Si5334K) may be functionally similar but require verification of the specific frequency plan and pin-control logic via their respective datasheets.

FAQ

What is the maximum output frequency supported?

Outputs can synthesize any frequency up to 350 MHz generally, with select configurations supporting frequencies up to 710 MHz depending on the output format.

How is the device configured?

The Si5334 is pin-controlled. Configuration data is stored in factory-programmed non-volatile memory (NVM) and loaded into RAM upon power-up, requiring no user intervention during operation.

Does the device support glitchless frequency adjustment?

While the standard Si5334 supports phase adjustment, specific variants in the family (such as Si5334G/H/J) offer pin-controlled frequency increment/decrement features for glitchless adjustments.
