SI5334C-B04687-GMR

Overview

The SI5334C-B04687-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 jitter. The device supports input frequencies up to 710 MHz and output formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. It operates with core supply voltages of 1.8 V, 2.5 V, or 3.3 V and features independent output voltage configurations.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential outputs with 0.7 ps RMS typical jitter.
• Flexible input reference options include external crystals (8–30 MHz) and clock inputs up to 710 MHz.
• Highly configurable output drivers support multiple signal formats (LVPECL, LVDS, HCSL, CMOS, SSTL, HSTL) with independent voltage levels.
• Pin-controlled configuration allows for glitchless frequency adjustments and phase offset programming.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm factory-programmed frequency plans and package variants. Confirm availability status through authorized distributors as inventory levels fluctuate. Ensure compliance with RoHS-6 and lead-free requirements specified in the datasheet.

Selection Notes

Select this component when low jitter and flexible output formatting are required for multi-standard systems. Verify that the desired output frequencies fall within the supported ranges for the chosen signal format. Ensure the application environment stays within the -40 to +85 °C operating temperature range.

Part Context

This part belongs to the Si5334 family of pin-controlled clock generators. The 'C' suffix typically denotes a specific revision or feature set within the series, while the numeric code indicates the factory-programmed frequency plan. The '-GMR' suffix identifies the tape-and-reel packaging format.

Replacement Considerations

Direct replacements must match the 24-QFN package and pinout. Verify that alternative devices support the same MultiSynth architecture and jitter specifications. Check for compatibility with existing pin-control logic if field-adjustable features are utilized.

FAQ
