SI5334M-B02080-GM

Overview

The SI5334M-B02080-GM 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 24-lead QFN package.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential outputs with 0.7 ps RMS typical jitter.
• Supports flexible input references: external crystals (8–30 MHz), CMOS (up to 200 MHz), and differential clocks (up to 710 MHz).
• Pin-controlled configuration with factory-programmed NVM; no I2C interface required.
• Includes spread spectrum modulation compliant with PCI Express standards 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 suffix 'M' indicates the inclusion of pin-controlled spread spectrum functionality as defined in the datasheet ordering information. Confirm that the factory-programmed frequency plan matches the target application requirements, as the device operates without user intervention upon power-up.

Selection Notes

Select this model when PCI Express compliant spread spectrum is required via pin control. Ensure the design accommodates the 24-QFN thermal characteristics and utilizes short PCB traces for crystal connections to maintain optimal jitter performance. Verify that the required output voltage levels align with the independently configurable VDDO supplies.

Part Context

This component belongs to the Si5334 family of pin-controlled clock generators. The 'M' suffix specifically denotes the variant equipped with spread spectrum increment/decrement pin control capabilities, distinguishing it from standard variants lacking this feature.

Replacement Considerations

Direct replacements must be selected from the Si5334 family with matching suffixes to ensure identical spread spectrum and pin-control configurations. Verify that alternative part numbers support the same output formats and frequency ranges.
