SI5334C-B05751-GM

Overview

The SI5334C-B05751-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 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, and HSTL with individual 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 the -40 to +85 °C range.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with 0.7 ps RMS typical jitter.
• Highly-configurable output drivers support LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats with independent voltage selection.
• Flexible input reference options include external crystals (8-30 MHz), CMOS (up to 200 MHz), and differential inputs (up to 710 MHz).
• Pin-controlled configuration allows for glitchless frequency adjustments and phase offset programming without I2C interfaces.

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 'C' in the part number against the manufacturer's ordering guide to confirm the exact feature set, such as phase increment capabilities or spread spectrum support. Ensure compatibility with the required output voltage levels and input reference frequencies before procurement.

Selection Notes

Select this component when low jitter and high flexibility are required for multi-standard clocking. Verify that the target output frequencies fall within the supported ranges for the chosen signal format (e.g., LVDS up to 710 MHz vs. CMOS up to 200 MHz). Confirm power supply requirements for both the core and individual output drivers.

Part Context

This part belongs to the Si5334 family of pin-controlled clock generators. The 'C' suffix typically denotes a specific configuration variant within the series, often related to standard frequency plans or specific pin-control features defined by Skyworks Solutions.

Replacement Considerations

Direct replacements must match the 24-QFN package and pinout. Consider other Si5334 variants (e.g., Si5334K, Si5334M) if spread spectrum or different control features are needed, but verify electrical parameter compatibility.

FAQ

What is the maximum output frequency supported?

The device supports output frequencies up to 710 MHz for select formats like LVPECL and LVDS, while formats like CMOS are limited to 200 MHz.

Does the SI5334C support I2C programming?

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

Can the output drivers operate at different voltage levels?

Yes, each of the four output drivers has an independent supply voltage (VDDOx) that can be configured to 1.5, 1.8, 2.5, or 3.3 V.
