SI5334K-B04339-GM

Overview

The SI5334K-B04339-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). Key electrical parameters include a core supply voltage range of 1.71 V to 3.63 V, operating temperatures from -40°C to +85°C, and a 24-lead QFN package.

Feature Summary

• MultiSynth Technology: Enables independent, any-frequency synthesis with zero ppm error on four differential outputs.
• Flexible Input/Output: Supports crystal inputs (8–30 MHz), CMOS/SSTL/HSTL/Differential inputs (up to 710 MHz), and configurable output formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL.
• Low Jitter Performance: Achieves 0.7 ps RMS typical random jitter across various standard interfaces.
• Spread Spectrum Capability: The 'K' suffix variant supports PCI Express compliant spread spectrum modulation for EMI reduction.

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 factory-programmed frequency plans and packaging details. Confirm availability status as distribution channels may vary. Ensure compatibility with required input reference sources and output load conditions before integration.

Selection Notes

Select this component when pin control is preferred over I2C configuration. Verify that the required output frequencies fall within the supported ranges (up to 350 MHz or specific higher frequencies up to 710 MHz). Ensure the design accommodates the necessary output driver supply voltages (VDDO) which can be independently set to 1.5, 1.8, 2.5, or 3.3 V.

Part Context

This part belongs to the Si5334 family of pin-controlled clock generators. The 'K' in the model number indicates support for spread spectrum functionality. Other variants in the series include pin-controlled phase adjustment (D/E/F) or frequency adjustment (G/H/J) features, but the K variant focuses on glitchless frequency step capabilities and EMI reduction via spread spectrum.

Replacement Considerations

Direct replacements within the same family require matching the pin control interface and output count. Variants like SI5334A, B, or C offer similar pin control but lack specific features like spread spectrum or advanced phase/frequency stepping found in other suffixes. Cross-model substitution requires verifying electrical compatibility and pinout alignment.
