SI5334M-B09995-GMR

Overview

The SI5334M-B09995-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) and clocks up to 710 MHz. Outputs are independently configurable for formats such as LVPECL, LVDS, HCSL, CMOS, SSTL, or HSTL with independent supply voltages of 1.5, 1.8, 2.5, or 3.3 V. It operates on a core supply of 1.8, 2.5, or 3.3 V within an industrial temperature range of –40 to +85 °C.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with 0 ppm accuracy.
• Low phase jitter performance of 0.7 ps RMS typical.
• Flexible input reference options: external crystal (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), or differential (5–710 MHz).
• Pin-controlled configuration with glitchless frequency increment/decrement capabilities.

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 'GMR' indicates tape-and-reel packaging when sourcing. Confirm that the factory-programmed frequency plan matches the design requirements, as the device operates immediately upon power-up without user intervention. Check current availability status as distribution may vary.

Selection Notes

Select this model for applications requiring pin-controlled flexibility and low jitter. Ensure the required output voltage levels (1.5V to 3.3V) match the target loads. Verify that the input source (crystal vs. clock) aligns with the supported frequency ranges specified in the datasheet.

Part Context

This component belongs to the Si5334 family of pin-controlled clock generators. The 'M' suffix typically denotes support for Spread Spectrum Clocking (SSC) compliant with PCI Express standards. The 'B09995' code represents a specific factory-programmed frequency plan.

Replacement Considerations

Direct replacements must be sought from the Si5334 family with matching suffixes for package and programming type. Verify that alternative part numbers support the same output formats and frequency plans, as these are factory-defined.

FAQ

What is the maximum output frequency?

Outputs can synthesize any frequency up to 350 MHz, with select frequencies supported up to 710 MHz.

How is the device configured?

The Si5334 is pin-controlled. Configuration data is stored in NVM and downloaded to RAM upon power-up, allowing immediate operation without software intervention.

Does the device support spread spectrum?

Yes, the 'M' series supports Spread Spectrum Clocking (SSC) compliant with PCI Express standards on outputs operating at 100 MHz.
