SI5334C-B05738-GM

Overview

The SI5334C-B05738-GM is a pin-controlled quad clock generator utilizing MultiSynth technology for independent, any-frequency synthesis on four differential outputs. It supports input frequencies from 5 to 710 MHz and generates output frequencies up to 350 MHz generally, with select configurations reaching 710 MHz. The device features low phase jitter of 0.7 ps RMS typ and zero ppm frequency accuracy. It operates on 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.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with 0.7 ps RMS typical phase jitter.
• Flexible input reference options include external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz).
• Highly-configurable output drivers support up to four differential outputs or eight single-ended outputs in mixed formats.
• Pin-controlled configuration allows for glitchless frequency adjustments and phase offset programming without I2C interface.

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 ordering suffix against the manufacturer's current documentation to confirm factory-programmed frequency plans and package variations. Confirm availability status through authorized distributors as supply conditions may vary. Ensure compatibility with required input/output signal formats and voltage levels before procurement.

Selection Notes

Select this component when pin control is preferred over I2C programmability for fixed-frequency applications. Verify that the required output frequencies fall within the supported ranges for the chosen output format (e.g., LVDS up to 710 MHz vs. CMOS up to 200 MHz). Ensure the design accommodates the 24-QFN package thermal requirements and PCB land pattern specifications.

Part Context

This part belongs to the Si5334 family of pin-controlled clock generators from Skyworks Solutions. The 'C' suffix typically denotes specific configuration parameters programmed at the factory. The device is designed to replace older clock synthesizers by offering higher flexibility and lower jitter in a compact 4x4 mm QFN package.

Replacement Considerations

Direct replacements must be sought from the Si5334 family with matching pin counts and electrical characteristics. Verify that alternative parts support the same output formats and frequency ranges. Note that different suffixes within the family may have distinct factory-programmed settings requiring re-verification.
