SI5334C-B05752-GM

Overview

The SI5334C-B05752-GM is a pin-controlled quad clock generator utilizing MultiSynth technology for independent, any-frequency synthesis on four differential outputs. It supports 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 accepts external crystals (8–30 MHz) or reference clocks (5–710 MHz). Outputs are configurable for LVPECL, LVDS, HCSL, CMOS, SSTL, or HSTL formats with independent supply voltages (1.5, 1.8, 2.5, or 3.3 V). The core operates at 1.8, 2.5, or 3.3 V in a 24-QFN package.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers with 0.7 ps RMS typical jitter.
• Flexible input support for external crystals (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), and differential inputs (5–710 MHz).
• Highly-configurable output drivers supporting LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats with independent voltage selection.
• Pin-controlled configuration with factory programming options and optional zero-delay mode implementation.

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 'B05752' against the manufacturer's current ordering guide to confirm the exact frequency plan and output configuration. Factory-programmed variants require strict adherence to the datasheet's ordering information table to ensure correct initialization parameters upon power-up.

Selection Notes

Select this component when independent frequency synthesis across four outputs is required without I2C interface complexity. Ensure the target output format (LVPECL, LVDS, etc.) matches the load requirements. Verify that the input source falls within the supported range of 8–30 MHz for crystals or 5–710 MHz for clock inputs.

Part Context

This part belongs to the Si5334 family of pin-controlled clock generators from Skyworks Solutions. It is distinct from I2C-programmable variants like the Si5338. The 'C' suffix typically denotes a specific feature set or revision within the pin-controlled lineup, differentiated by the internal NVM content defined by the numeric code.

Replacement Considerations

Direct replacements must match the 24-QFN package and pinout. Consider Si5334 variants with identical frequency plans. For applications requiring I2C control instead of pin control, the Si5338 series may be functionally equivalent but requires software reconfiguration.
