SI5338N-B04890-GM

Overview

The SI5338N-B04890-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, 2.5, 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 clocks.

Feature Summary

• MultiSynth™ technology enables zero ppm precision synthesis on four independent outputs
• Supports LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL output formats
• Low phase jitter performance of 0.7 ps RMS typical
• Flexible input options: external crystal (8-30 MHz), CMOS (5-200 MHz), or differential (5-710 MHz)

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS applications
• Ethernet switch and router timing

• Broadcast video/audio timing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet revision to confirm pinout and configuration settings. Ensure compatibility with the required I²C bus voltage levels and check for moisture sensitivity classification prior to surface mount assembly.

Selection Notes

Select this component when independent frequency synthesis across multiple domains is required. Confirm that the target output signal format (LVDS, LVPECL, etc.) and maximum frequency requirements align with the device's capabilities. Validate power supply constraints against the 1.8V, 2.5V, or 3.3V core supply options.

Part Context

This part belongs to the Si5338 family of I²C-programmable clock generators. It is designed to replace multiple discrete oscillators in complex digital systems. The 'N' suffix typically denotes a specific factory configuration or binning within the broader Si5338 product line.

Replacement Considerations

Direct replacements within the Si5338 family may require reprogramming via ClockBuilder Pro software to match the original design's frequency plan and output configurations. Verify pin-to-pin compatibility if substituting with other Si533x variants.
