SI5334C-B04801-GM

Overview

The SI5334C-B04801-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 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 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 with factory programming via NVM; includes phase adjustment (<20 ps steps) and loss-of-lock/signal alarms.

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 'B04801' against the manufacturer's datasheet to confirm the exact frequency plan and pin control settings. Factory-programmed configurations are unique to each part number; generic family data does not define the operational frequencies for this specific order code.

Selection Notes

Select this component when low jitter and high flexibility are required for mixed-format clock distribution. Ensure the application utilizes the pin-control interface rather than I2C. Verify that the required output frequencies fall within the supported ranges: up to 350 MHz for standard synthesis and select higher frequencies up to 710 MHz.

Part Context

This part belongs to the Si5334 family of pin-controlled clock generators. The 'C' in the model number typically denotes a specific feature set or revision within the series, while the numeric suffix defines the custom frequency plan programmed into the internal non-volatile memory at the factory.

Replacement Considerations

Direct replacements must match the 24-QFN package and pinout. Other Si5334 variants (e.g., Si5334D, Si5334G) offer additional features like frequency increment/decrement but require verification of electrical compatibility and pin mapping before substitution.

FAQ

Does the SI5334C support I2C programming?

No, the Si5334C is a pin-controlled device. Configuration is handled via hardware pins and factory-programmed non-volatile memory.

What is the maximum output frequency?

Outputs can be synthesized up to 350 MHz generally, with select frequencies supported up to 710 MHz depending on the specific divider configuration.

Can each output have a different voltage level?

Yes, each output driver has an independent supply pin (VDDOx), allowing for independent voltage levels of 1.5, 1.8, 2.5, or 3.3 V.
