SI5334C-B05946-GM

Overview

The SI5334C-B05946-GM is a pin-controlled quad clock generator utilizing MultiSynth technology for independent, any-frequency synthesis on four differential outputs. It supports input frequencies up to 710 MHz and generates output clocks with zero ppm frequency error and typical phase jitter of 0.7 ps RMS. The device operates from a core supply voltage of 1.8 V, 2.5 V, or 3.3 V, with independently configurable output drivers supporting formats such as LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. Packaged in a 24-lead QFN (4x4 mm) suitable for surface mount applications.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with true 0 ppm accuracy.
• Low phase jitter performance of 0.7 ps RMS typical across all outputs.
• Flexible input reference options including external crystals (8–30 MHz), CMOS (up to 200 MHz), and differential inputs (up to 710 MHz).
• Highly-configurable output drivers support multiple signal formats (LVPECL, LVDS, HCSL, CMOS, SSTL, HSTL) with independent supply voltages.

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 ordering suffix against the manufacturer's current documentation to confirm factory-programmed frequency plans and configuration parameters. Confirm package marking and RoHS compliance status prior to procurement.

Selection Notes

Select this component when low jitter and flexible output format configuration are required. Ensure the application utilizes the pin-control interface rather than I2C. Verify that the required output frequencies fall within the supported ranges for the selected driver types.
