SI5338Q-B05204-GMR

Application Specific Clock/Timing Overview

The SI5338Q-B05204-GMR is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency with 0 ppm precision on four independent outputs, supporting formats including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. The device operates from a single core supply of 1.8 V, 2.5 V, or 3.3 V, with output drivers configurable to 1.5 V, 1.8 V, 2.5 V, or 3.3 V. Key electrical parameters include a typical phase jitter of 0.7 ps RMS, a maximum input frequency of 710 MHz, and a maximum output frequency of 710 MHz for differential signals. It features glitchless frequency adjustments in 1 ppm steps and independent phase adjustment with <20 ps accuracy.

Application Specific Clock/Timing Feature Summary

• I2C-programmable synthesis with true zero ppm frequency accuracy
• Low phase jitter of 0.7 ps RMS typ across all outputs
• Independent output voltage selection (1.5/1.8/2.5/3.3 V) per driver
• Glitchless frequency increment/decrement in 1 ppm steps

Application Specific Clock/Timing Applications

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

Application Specific Clock/Timing Procurement Notes

Verify the specific ordering suffix B05204 against the manufacturer's official documentation to confirm the exact pre-programmed frequency plan and pin configuration. Confirm that the GMR suffix corresponds to the required reel packaging quantity and moisture sensitivity level for the assembly process.

Application Specific Clock/Timing Selection Notes

Select this component when independent frequency synthesis with low jitter is required for multiple domains. Ensure the input reference matches the supported ranges: external crystal (8-30 MHz), CMOS (5-200 MHz), or differential (up to 710 MHz). Validate that the target output frequencies fall within the limits of the chosen signal format, such as 710 MHz for LVDS/LVPECL or 200 MHz for CMOS.

Application Specific Clock/Timing Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces discrete crystal oscillators by providing flexible frequency translation and buffering. The QFN-24 package offers a compact footprint suitable for high-density PCB layouts in telecom and networking equipment.

Application Specific Clock/Timing Replacement Considerations

Direct replacements must be sought from the Skyworks Si5338 family. Verify compatibility regarding the output count, package type, and programming interface. Note that different suffixes may alter the factory-programmed frequencies or output configurations.
