SI5334C-B04687-GM

Overview

The SI5334C-B04687-GM is a pin-controlled quad clock generator utilizing MultiSynth technology for independent, any-frequency synthesis on four differential outputs. It supports input frequencies from 5 to 710 MHz and generates output frequencies up to 350 MHz generally, with select configurations reaching 710 MHz. The device features low phase jitter of 0.7 ps RMS typical and zero ppm frequency accuracy. It operates on a core supply voltage of 1.8 V, 2.5 V, or 3.3 V within an industrial temperature range of -40 to +85 °C.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers.
• Highly-configurable output drivers support LVPECL, LVDS, HCSL, CMOS, SSTL, or HSTL formats.
• Low phase jitter specification of 0.7 ps RMS typical with true 0 ppm frequency accuracy.
• Flexible input reference options including external crystals (8-30 MHz) and differential inputs (up to 710 MHz).

Applications

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

Procurement Notes

Verify the specific suffix 'C' against the datasheet's ordering information table to confirm the exact configuration, such as spread spectrum capabilities or frequency increment/decrement features, as these vary across the Si5334 family. Ensure compatibility with the required output voltage levels and package type before procurement.

Selection Notes

Select this component when pin control is preferred over I2C programming. Verify that the required output frequencies fall within the supported ranges for the chosen output format (e.g., LVDS up to 710 MHz). Confirm that the application requires the specific jitter performance and power supply constraints provided by the Si5334C variant.

Part Context

The Si5334 series comprises multiple variants differentiated by suffixes indicating specific feature sets like spread spectrum or frequency adjustment capabilities. The Si5334C is part of this family, designed for high-performance clock generation in a compact 24-QFN package. It shares the core MultiSynth architecture with other models but may lack certain advanced dynamic adjustment features found in higher-tier variants.

Replacement Considerations

Direct replacements within the Si5334 family require matching the output count, frequency range, and package. Variants like SI5334M or SI5334K offer additional features such as spread spectrum or frequency increment/decrement. Ensure the substitute part number matches the specific electrical characteristics and pinout requirements of the original design.
