SI5334C-B04810-GMR

Overview

The SI5334C-B04810-GMR is a pin-controlled quad clock generator utilizing MultiSynth technology for independent, any-frequency synthesis on four differential outputs. It supports input frequencies up to 710 MHz and generates output clocks with zero ppm frequency error and typical phase jitter of 0.7 ps RMS. The device features highly configurable output drivers supporting LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats with independent supply voltages. Operating from a core supply of 1.8 V, 2.5 V, or 3.3 V, it is housed in a 24-lead QFN package.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers
• Low phase jitter: 0.7 ps RMS typical
• High-precision synthesis allows true 0 ppm frequency accuracy on all outputs
• Flexible input reference: External crystal (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), Differential (5–710 MHz)

Applications

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

Procurement Notes

Verify the specific factory-programmed frequency plan associated with the B04810 suffix against system requirements. Confirm that the standard pin-controlled configuration meets design needs as no I2C interface is provided. Ensure compatibility with the specified operating temperature range of -40 to +85 °C.

Selection Notes

Select this model when low jitter and precise frequency synthesis are required without digital programming interfaces. Verify that the target output frequencies fall within the supported ranges for the chosen signal format (e.g., up to 350 MHz for LVDS/LVPECL). Ensure the application can accommodate the 24-QFN package footprint.

Part Context

This component belongs to the Si5334 family of pin-controlled clock generators. The 'C' suffix indicates a specific configuration variant within the series, distinct from other variants like the M or K series which may support spread spectrum or different control features. It is manufactured by Skyworks Solutions, Inc.

Replacement Considerations

Direct replacements must match the 24-QFN package and pinout. Verify if alternative Si5334 variants (e.g., Si5334M) provide necessary features like spread spectrum if EMI reduction is critical, noting that functional differences exist between suffixes.
