SI5334C-B05946-GMR

Overview

The SI5334C-B05946-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 input frequencies up to 710 MHz and output formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. It operates with core supply voltages of 1.8 V, 2.5 V, or 3.3 V and features independent output voltage control per driver.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential outputs with 0.7 ps RMS typical jitter.
• Flexible input reference options: external crystal (8-30 MHz), CMOS (5-200 MHz), SSTL/HSTL (5-350 MHz), or differential (5-710 MHz).
• Highly configurable output drivers support LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats with independent voltage selection.
• Pin-controlled configuration with factory-programmable NVM for immediate operation upon power-up.

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 frequency plan associated with the B05946 suffix against the official Skyworks datasheet, as this code defines the programmed output frequencies. Confirm package availability and lead times through authorized distributors, as stock levels vary by region.

Selection Notes

Select this part when low jitter (<1 ps RMS) and flexible output formats are required. Ensure the application utilizes pin-control rather than I2C, as this model lacks an I2C interface. Verify that the required output frequencies fall within the supported ranges for the chosen output format.

Part Context

This component belongs to the Si5334 family of pin-controlled clock generators. It is distinct from the Si5338 series, which typically includes I2C programmability. The 'C' in the part number indicates a specific configuration variant within the broader Si5334 product line.

Replacement Considerations

Direct replacements must be sought from the Si5334 family with matching frequency plans. Cross-model substitution with Si5338 requires verification of programming interface differences (pin vs. I2C).
