SI5338C-B04167-GMR

Overview

The SI5338C-B04167-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 V, 2.5 V, or 3.3 V and features low phase jitter of 0.7 ps RMS typical. Configuration is managed via an I²C/SMBus interface, allowing for flexible input references including crystals, CMOS, and differential clocks.

Feature Summary

• MultiSynth™ technology enables zero ppm precision frequency synthesis on four independent outputs.
• Supports diverse output formats: LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL.
• 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).

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 B04167 against the manufacturer's current datasheet to confirm factory programming parameters. Ensure the QFN-24 package land pattern matches the recommended PCB layout in the official documentation. Confirm I²C pull-up voltage compatibility if operating below 2.5 V.

Selection Notes

Select this model when independent frequency synthesis across four outputs is required with low jitter. Verify that the desired output signal formats (LVDS, LVPECL, etc.) and voltage levels (1.5 V to 3.3 V) are supported by the specific configuration. Check input reference constraints, such as maximum differential input frequency of 710 MHz.

Part Context

This component belongs to the Si5338 family of I²C-programmable clock generators. It replaces multiple discrete oscillators with a single IC solution. The 'GMR' suffix indicates tape-and-reel packaging, while 'B04167' denotes specific factory-programmed register settings for frequency and format configuration.

Replacement Considerations

Direct pin-to-pin replacements within the same family include other Si5338 variants with different factory presets (e.g., SI5338A, SI5338Q). Ensure the replacement part supports the required output frequencies and formats. Cross-model substitution requires reprogramming via ClockBuilder Pro software.
