SI5338Q-B04069-GM

Application Specific Clock/Timing Overview

The SI5338Q-B04069-GM is a programmable quad clock generator from Skyworks Solutions, 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 1.8 V, 2.5 V, or 3.3 V core supply, drawing a typical current of 45 mA. Key electrical parameters include a maximum input frequency of 710 MHz, a maximum output frequency of 710 MHz for differential signals, and a typical phase jitter of 0.7 ps RMS. It is housed in a 24-lead QFN package.

Application Specific Clock/Timing Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers with 0 ppm precision.
• Supports flexible input references including external crystals (8–30 MHz), CMOS (up to 200 MHz), and differential inputs (up to 710 MHz).
• Features low phase jitter of 0.7 ps RMS typical and glitchless frequency adjustments via independent increment/decrement features.
• Configurable spread spectrum (SSC) allows any frequency from 5 to 350 MHz with spread rates from 0.5% to 5.0%.

Application Specific Clock/Timing Applications

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

Application Specific Clock/Timing Procurement Notes

Verify the specific ordering suffix B04069 against the manufacturer's official documentation to confirm pre-programmed register settings. Confirm the package type is the 24-lead QFN and check humidity sensitivity handling requirements during storage and assembly.

Application Specific Clock/Timing Selection Notes

Select this component when designing systems requiring multiple independent clock frequencies from a single IC. Ensure the required output voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) match the load requirements. Verify that the input reference source falls within the supported frequency ranges for the chosen format.

Application Specific Clock/Timing Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It is designed to replace multiple discrete crystal oscillators or buffers. The 'Q' suffix typically denotes automotive grade qualification, while 'GM' indicates tape and reel packaging.

Application Specific Clock/Timing Replacement Considerations

Direct replacements must maintain the 24-QFN package and I2C interface. Check if alternative Skyworks models like the SI5338A or SI5338B offer compatible pinouts and sufficient output drive capabilities for the specific application loads.
