SI5338N-B06121-GM

Overview

The SI5338N-B06121-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 frequencies up to 710 MHz. The device 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, allowing for flexible input references including crystals, CMOS, and differential signals.

Feature Summary

• Four independent output drivers supporting LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats
• Low phase jitter performance of 0.7 ps RMS typical
• Flexible input options: external crystal (8–30 MHz), CMOS (5–200 MHz), and differential (5–710 MHz)
• Independent output voltage selection per driver: 1.5 V, 1.8 V, 2.5 V, or 3.3 V

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet revision to confirm pinout and electrical characteristics. Ensure compatibility with the intended I²C bus voltage levels, as the device supports standard and fast mode operations across varying supply voltages.

Selection Notes

Select this component when zero ppm frequency accuracy is required across multiple independent clocks. Consider the available output formats and supply voltages to match the load requirements. Verify that the input reference frequency falls within the supported ranges for the desired configuration.

Part Context

This part belongs to the Si5338 family of I²C-programmable clock generators. The family is designed to replace multiple discrete oscillators with a single low-jitter solution. The specific model indicates a factory-programmed variant optimized for specific frequency and format configurations.

Replacement Considerations

Direct replacements within the Si5338 family may require reprogramming via ClockBuilder Pro software to match the original frequency plan. Verify package dimensions and pin assignments if substituting with other variants in the series.
