SI5334C-B05500-GMR

Overview

The SI5334C-B05500-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 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 an industrial temperature range of –40 to +85 °C.

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 loss-of-lock/signal alarm and optional zero-delay mode.

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 B05500 against the official Skyworks datasheet to confirm the exact pre-programmed frequency plan and output configurations. As this is a custom part number, availability may be limited compared to standard SKUs. Confirm RoHS compliance and moisture sensitivity levels prior to procurement.

Selection Notes

Select this model when pin control is preferred over I2C programmability. Ensure the required output frequencies fall within the valid ranges for the chosen signal format (e.g., LVPECL/LVDS up to 710 MHz, CMOS up to 200 MHz). Verify that the input reference source matches the supported frequency bands and impedance requirements.

Part Context

This component belongs to the Si5334 family of pin-controlled clock generators. The 'C' suffix typically denotes a specific feature set or revision within the series, while 'B05500' indicates a unique factory-programmed frequency plan. It shares the same 24-QFN package and core architecture as other Si5334 variants.

Replacement Considerations

Direct replacements must match the 24-QFN footprint and pinout. Functionally equivalent parts from the Si5334 family (e.g., Si5334M or Si5334K) may require reprogramming if they lack the identical factory settings. Verify compatibility with existing input sources and output load requirements.
