SI5334M-B04346-GMR

Overview

The SI5334M-B04346-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 0.7 ps RMS typical phase jitter. Outputs support LVPECL, LVDS, HCSL, CMOS, SSTL, or HSTL formats with independent voltage selection (1.5V to 3.3V). The device accepts external crystals (8-30 MHz) or reference clocks (up to 710 MHz). It features glitchless frequency increment/decrement in 1 ppm steps via pin control and operates on a single core supply of 1.8V, 2.5V, or 3.3V within the -40°C to +85°C range.

Feature Summary

• MultiSynth Technology: Enables independent, any-frequency synthesis on four differential output drivers with low jitter and zero ppm accuracy.
• Flexible Output Drivers: Supports up to four differential or eight single-ended outputs; configurable for LVPECL, LVDS, HCSL, CMOS, SSTL, or HSTL.
• Pin-Controlled Frequency Adjustment: Glitchless frequency increment/decrement in 1 ppm steps via dedicated pins.
• Low Phase Jitter: Typical RMS jitter of 0.7 ps across all outputs.

Applications

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

Procurement Notes

Verify the specific suffix 'B04346' against the manufacturer's official documentation to confirm the exact factory-programmed frequency plan and configuration. Ensure the ordering code matches the required output frequencies and signal formats before procurement.

Selection Notes

Select this component when pin-controlled configuration is preferred over I2C programmability. Verify that the required output frequencies fall within the supported ranges (up to 350 MHz standard, select up to 710 MHz) and that the input reference source (crystal or clock) aligns with the device's input specifications.

Part Context

This part belongs to the Si5334 family of pin-controlled clock generators. The 'M' suffix indicates support for Spread Spectrum Clocking (SSC) compliant with PCI Express standards. The 'GMR' suffix denotes the tape-and-reel packaging format suitable for automated surface-mount assembly.

Replacement Considerations

Direct replacements must be verified through Skyworks Solutions based on the specific frequency plan encoded in the NVM. Other Si5334 variants may differ in configuration capabilities or feature sets such as SSC support.

FAQ

Does the SI5334M-B04346-GMR support I2C programming?

No, the Si5334 is a pin-controlled device and does not provide an I2C interface. Configuration is handled via hardware pins and factory-programmed NVM.

What is the maximum operating temperature for this device?

The device supports an industrial temperature range from -40°C to +85°C.

Can the output voltage levels be adjusted independently?

Yes, each output driver has its own supply voltage (VDDOx), allowing independent configuration for voltages such as 1.5V, 1.8V, 2.5V, or 3.3V.
