SI5334K-B04854-GMR

Overview

The SI5334K-B04854-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. The device supports input frequencies up to 710 MHz and output formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. It features spread spectrum capabilities compliant with PCI Express standards for EMI reduction. Powered by a 1.8 V, 2.5 V, or 3.3 V core supply, it operates within an industrial temperature range of -40°C to +85°C in a compact 24-lead QFN package.

Feature Summary

• MultiSynth Technology: Enables independent, any-frequency synthesis on four differential outputs with low jitter (0.7 ps RMS typ) and true 0 ppm accuracy.
• Flexible Input/Output: Accepts external crystals (8–30 MHz) or clocks (5–710 MHz); supports LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL output formats.
• Spread Spectrum: Supports PCI Express compliant spread spectrum modulation on all 100 MHz outputs for EMI reduction.
• Pin-Controlled Operation: Factory-programmed configuration activates automatically upon power-up without requiring I2C communication.

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 current documentation to confirm factory-programmed frequency plans and output configurations. Confirm availability status directly with authorized distributors as inventory levels fluctuate. Ensure compliance with RoHS-6 and Pb-free manufacturing standards specified in the datasheet.

Selection Notes

Select this model for applications requiring glitch-free frequency generation with strict jitter constraints. Verify that the required output voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) match the target load requirements. Ensure the input reference source falls within the supported frequency ranges for the chosen input type (crystal vs. differential/single-ended clock).

Part Context

This component belongs to the Si5334 family of pin-controlled clock generators. The 'K' suffix indicates support for spread spectrum functionality compliant with PCI Express standards. The 'B04854' code defines the specific factory-programmed frequency plan and output driver configurations.

Replacement Considerations

Direct replacements must be sought from the Si5334 family with matching pin counts and package types. Verify that alternative part numbers support the same spread spectrum requirements and output voltage levels. Cross-reference specific frequency plans if exact substitution is required.
