SI5334C-B05751-GMR

Overview

The SI5334C-B05751-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 phase 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 from a core supply of 1.8, 2.5, or 3.3 V in a 24-lead QFN package.

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 operation with factory-programmed NVM configuration; includes loss-of-lock/signal alarm and optional zero-delay mode.

Applications

• Ethernet switch/router clocking
• PCI Express 2.0/3.0 common clock generation
• Processor and FPGA clocking
• Broadcast video/audio timing
• MSAN/DSLAM/PON systems

Procurement Notes

Verify the specific ordering suffix B05751 against the manufacturer's current documentation to confirm the exact frequency plan and pin control settings. Factory programming defines the operational parameters; ensure the programmed configuration matches the target application requirements before integration.

Selection Notes

Select this component when low jitter and high precision are required for multi-output clock distribution. Ensure the input reference source matches the supported frequency ranges. Verify that the required output signal formats and voltage levels are compatible with the individually configurable output drivers.

Part Context

This part belongs to the Si5334 family of pin-controlled clock generators. The 'C' suffix indicates a specific variant within the series, typically denoting pin-control features without spread spectrum capabilities compared to other variants like K, L, M, or G/H/J which may offer frequency increment/decrement or spread spectrum functions.

Replacement Considerations

Direct replacements must match the 24-QFN package and pinout. Verify that alternative parts support the same output formats and voltage levels. Check if the replacement offers equivalent jitter performance and input flexibility. Note that custom frequency plans are unique to each part number.
