SI5338Q-B04735-GMR

Application Specific Clock/Timing Overview

The SI5338Q-B04735-GMR is a programmable quad clock generator utilizing MultiSynth technology to synthesize any frequency on four independent output drivers. It supports differential and single-ended outputs with formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. The device operates from a core supply of 1.8 V, 2.5 V, or 3.3 V and accepts inputs up to 710 MHz. Key electrical parameters include a typical phase jitter of 0.7 ps RMS, a maximum input frequency of 710 MHz, and an operating temperature range of -40°C to +85°C.

Application Specific Clock/Timing Feature Summary

• I2C/SMBus programmable interface for flexible configuration
• Four independent output drivers supporting any frequency synthesis
• Low phase jitter performance (0.7 ps RMS typical)
• Supports multiple output voltage levels (1.5 V, 1.8 V, 2.5 V, 3.3 V)

Application Specific Clock/Timing Applications

• PCIe Gen 1/2/3/4 common clock and SRNS generation
• Ethernet switch and router timing
• Processor and FPGA clocking
• Broadcast video/audio timing

Application Specific Clock/Timing Procurement Notes

Verify the specific ordering suffix B04735 against the manufacturer's current documentation to confirm factory programming details. Ensure compatibility with I2C bus voltage requirements if operating below 2.5 V. Confirm package integrity for the 24-lead QFN form factor upon receipt.

Application Specific Clock/Timing Selection Notes

Select this component when zero ppm frequency accuracy and low jitter are required across multiple output domains. Verify that the desired output frequencies fall within the supported ranges for the chosen signal format (e.g., up to 710 MHz for LVDS/LVPECL). Ensure the design accommodates the 4x4 mm QFN-24 thermal requirements.

Application Specific Clock/Timing Part Context

This part belongs to the Si5338 family of high-performance clock generators. The 'Q' in the model number typically denotes automotive-grade qualification or specific reliability standards, while 'GMR' indicates tape-and-reel packaging. The base Si5338 architecture provides the underlying MultiSynth synthesis capabilities.

Application Specific Clock/Timing Replacement Considerations

Direct pin-compatible replacements within the same series include other Si5338 variants such as SI5338Q-B-GMR or SI5338J-B-GMR, provided the internal programming matches the application requirements.
