SI5338Q-B04386-GMR

Application Specific Clock/Timing Overview

The SI5338Q-B04386-GMR is a programmable clock generator from Skyworks Solutions, utilizing MultiSynth technology to synthesize any frequency on four output drivers. It supports differential and single-ended outputs with frequencies up to 710 MHz. The device features low phase jitter of 0.7 ps RMS typical, independent output voltage configurations (1.5V, 1.8V, 2.5V, or 3.3V), and flexible input references including crystals, CMOS, SSTL/HSTL, and differential signals. Powered by a single core supply of 1.8V, 2.5V, or 3.3V, it operates within a temperature range of -40°C to +85°C in a 24-lead QFN package.

Application Specific Clock/Timing Procurement Notes

Verify the specific ordering suffix B04386 against the manufacturer's official documentation to confirm the exact pre-programmed frequency plan and output configuration. Ensure compatibility with I2C/SMBus interface requirements and check for moisture sensitivity handling instructions during assembly.

Application Specific Clock/Timing Selection Notes

Select this component when zero ppm frequency accuracy and low jitter are critical for multiple asynchronous clocks. Consider the available input reference types and required output voltage levels for each driver. Verify that the maximum output frequency requirements do not exceed 710 MHz for differential outputs or 200 MHz for CMOS outputs.

Application Specific Clock/Timing Part Context

This part belongs to the Si5338 family of I2C-programmable quad clock generators. It replaces discrete oscillators and frequency translators in complex digital systems. The 'GMR' suffix indicates tape and reel packaging suitable for automated surface-mount assembly.

Application Specific Clock/Timing Replacement Considerations

Direct pin-to-pin replacements within the same family may include other Si5338 variants with different pre-programmed frequencies. Ensure the substitute part supports the required output formats and jitter specifications for the target application.
