SI5334C-B05192-GMR

Overview

The SI5334C-B05192-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 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 and router clocking
• PCI Express 2.0/3.0 timing
• Processor and FPGA clock generation
• Broadcast video and audio synchronization

Procurement Notes

Verify the specific suffix 'B05192' against the official Skyworks datasheet to confirm the exact factory-programmed frequency plan and output configurations. Ensure compatibility with the required input reference source and output load conditions before procurement.

Selection Notes

Select this component when low jitter (<1 ps RMS) and high flexibility in output formats are required. Verify that the target frequencies fall within the supported ranges for the chosen output driver types (e.g., LVDS up to 710 MHz, CMOS up to 200 MHz). Confirm power supply requirements for both the core and individual output buffers.

Part Context

This part belongs to the Si5334 family of pin-controlled clock generators. The 'C' variant typically denotes specific pin-control features compared to other sub-families like 'M' or 'K'. It is designed for space-constrained applications requiring multiple clock domains from a single package.

Replacement Considerations

Direct replacements must match the 24-QFN package and pinout. Verify if alternative Skyworks models (e.g., Si5334M or Si5334K) provide the necessary spread spectrum or frequency increment features if those were critical to the original design.
