SI5334K-B04338-GM

Overview

The SI5334K-B04338-GM is a pin-controlled, low-jitter 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 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, typical core current of 45 mA, and typical RMS jitter of 0.7 ps. It operates within an industrial temperature range of –40 °C to +85 °C.

Feature Summary

• MultiSynth Technology: Enables independent, any-frequency synthesis with zero ppm error on four differential outputs.
• Flexible Output Drivers: Supports LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats with independent output supply voltages (1.5, 1.8, 2.5, or 3.3 V).
• Pin-Controlled Operation: Features simple pin control for configuration without I2C interface; includes LOSLOL alarm and OEB pin.
• Spread Spectrum Capability: Supports PCI Express 2.0 compliant spread spectrum on 100 MHz outputs 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 official documentation to confirm factory-programmed frequency plans and package variants. Confirm RoHS compliance status through the latest datasheet revision. Ensure input signal slew rates meet specifications for optimal jitter performance.

Selection Notes

Select this component when pin-controlled operation is required instead of I2C programmability. Verify that the target output frequencies fall within the supported ranges (up to 350 MHz standard, up to 710 MHz for select configurations). Ensure the application can accommodate the 4x4 mm QFN-24 package footprint and thermal requirements.

Part Context

This part belongs to the Si5334 family of clock generators. The 'K' suffix in the model number indicates support for Spread Spectrum Clocking (SSC), distinguishing it from other variants like the Si5334D/E/F (phase adjustment) or Si5334G/H/J (frequency adjustment).

Replacement Considerations

Direct replacements must be verified via Skyworks Solutions cross-reference tools. Pin-compatible alternatives may exist within the Si5334 series but require validation of functional differences such as SSC support or output driver capabilities.
