SI5338N-B06122-GM

Overview

The SI5338N-B06122-GM is a programmable quad clock generator from Skyworks Solutions. It utilizes MultiSynth technology to synthesize any frequency on four independent output drivers with 0 ppm precision. The device supports differential and single-ended outputs, including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats. It operates from a single core supply of 1.8 V, 2.5 V, or 3.3 V and features low phase jitter of 0.7 ps RMS typical. Configuration is performed via an I2C/SMBus interface.

Feature Summary

• I2C-programmable synthesis for any frequency up to 710 MHz
• Four independent output drivers supporting multiple signal formats
• Low phase jitter performance (0.7 ps RMS typical)
• Flexible input reference options including crystals and differential clocks

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm pinout and configuration settings. Ensure compatibility with the required I2C bus voltage levels and check for moisture sensitivity handling requirements during storage and assembly.

Selection Notes

Select this component when zero ppm frequency accuracy across multiple outputs is required. Verify that the desired output frequencies fall within the supported ranges for the chosen signal format (e.g., LVDS up to 710 MHz, CMOS up to 200 MHz). Confirm that the input reference source matches the device's supported input types.

Part Context

This part belongs to the Si5338 family of high-performance clock generators. The family is characterized by its ability to replace multiple discrete oscillators with a single integrated solution, offering space savings and design flexibility through software-defined configurations.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the Si5338 series. Verify that any substitute part supports the same output formats and frequency ranges required by the application.
