SI5334K-B04797-GMR

Overview

The SI5334K-B04797-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 low phase jitter (0.7 ps RMS typ). The device supports flexible input references including crystals (8–30 MHz) or clocks up to 710 MHz. Outputs are independently configurable for formats such as LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL with individual supply voltages of 1.5, 1.8, 2.5, or 3.3 V. It operates from a core supply of 1.8, 2.5, or 3.3 V in a 24-QFN package.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with 0 ppm accuracy.
• Low phase jitter performance: 0.7 ps RMS typical.
• Supports PCI Express 2.0 compliant spread spectrum modulation on 100 MHz outputs.
• Flexible input options: external crystal (8-30 MHz), CMOS (up to 200 MHz), or differential clock (up to 710 MHz).

Applications

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

Procurement Notes

Verify the specific suffix B04797 against the official datasheet ordering information to confirm the exact factory-programmed frequency plan. Confirm availability status through authorized distributors as lead times may vary.

Selection Notes

Select this variant if PCI Express 2.0 compliant spread spectrum is required. Ensure the application utilizes pin control rather than I2C, as this device lacks an I2C interface. Verify that the required output frequencies fall within the supported ranges for the chosen signal format.

Part Context

This component belongs to the Si5334 family of pin-controlled clock generators. The 'K' suffix indicates support for PCI Express 2.0 compliant spread spectrum. Other variants include D/E/F (phase adjustment), G/H/J (frequency adjustment), and L/M (spread spectrum).

Replacement Considerations

Direct replacements must be sought from the Si5334 family with matching suffixes for functional parity. Verify that alternative part numbers support the same spread spectrum requirements and pin control configuration.
