SI5334C-B05738-GMR

Overview

The SI5334C-B05738-GMR is a pin-controlled quad clock generator utilizing MultiSynth technology for independent, any-frequency synthesis on four differential outputs. It supports 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 accepts external crystals (8–30 MHz) or reference clocks (5–710 MHz). Each output driver is independently configurable for signal format (LVPECL, LVDS, HCSL, CMOS, SSTL, HSTL) and voltage (1.5, 1.8, 2.5, or 3.3 V). The core supply operates at 1.8, 2.5, or 3.3 V.

Feature Summary

• Low-power MultiSynth technology enables independent, any-frequency synthesis on four differential output drivers
• Highly-configurable output drivers support up to four differential outputs or eight single-ended clock outputs
• Low phase jitter: 0.7 ps RMS typ; High-precision synthesis allows true 0 ppm frequency accuracy
• Flexible input reference: External crystal (8–30 MHz), CMOS (5–200 MHz), SSTL/HSTL (5–350 MHz), Differential (5–710 MHz)

Applications

• Ethernet switch/router
• PCI Express 2.0/3.0
• Broadcast video/audio timing
• Processor and FPGA clocking
• MSAN/DSLAM/PON

Procurement Notes

Verify the specific factory-programmed frequency plan associated with the B05738 suffix against the system requirements. Confirm that the required output formats and voltages match the device's capabilities. Check current availability status as distribution may vary. Ensure proper handling for moisture sensitivity level during assembly.

Selection Notes

Select this component when pin control is preferred over I2C programming. Verify that the target frequencies fall within the supported ranges for the desired output formats (e.g., LVDS/LVPECL up to 710 MHz, CMOS up to 200 MHz). Ensure the input reference source matches the compatible frequency range. Consider the 4x4 mm QFN package size constraints.

Part Context

This part belongs to the Si5334 family of pin-controlled clock generators from Skyworks Solutions. The 'C' in the model number typically denotes a specific configuration variant within the series, often related to the absence of spread spectrum or specific pin-out configurations compared to other variants like K, L, M, or G, H, J. It is designed for high-performance clock generation in datacom and telecom applications.

Replacement Considerations

Direct replacements must be from the Si5334 family with matching pinout and electrical characteristics. Verify if the replacement part supports the same output formats and frequency ranges. Note that different suffixes may imply different factory-programmed frequencies or feature sets (e.g., spread spectrum capability). Consult Skyworks for cross-reference validation.
