SI5338N-B04908-GMR

Overview

The SI5338N-B04908-GMR 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 on 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

• I2C-programmable synthesis of any frequency on four independent outputs
• Low phase jitter performance of 0.7 ps RMS typical
• Supports LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL output formats
• Flexible input reference options: external crystal (8-30 MHz), CMOS, or differential inputs up to 710 MHz

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS applications
• Ethernet switch and router timing
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards and MSAN/DSLAM/PON systems

Procurement Notes

Verify the specific ordering suffix B04908 against the manufacturer's official documentation to confirm the programmed frequency plan and pinout configuration. 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 and independent output voltage domains are required. Verify that the desired output signal formats (LVPECL, LVDS, etc.) and maximum operating frequencies align with the device capabilities. Confirm that the available input reference sources match the supported ranges for crystal or direct drive inputs.

Part Context

This part belongs to the Si5338 family of high-performance clock generators. The 'N' in the part number typically denotes a specific factory programming configuration or feature set within the broader Si5338 product line, which shares the same QFN-24 package and core architecture.

Replacement Considerations

Direct replacements must be sought from the Si5338 family with matching programming configurations. Cross-referencing the exact frequency plan and output driver types is essential as generic Si5338 parts may have different default settings.
