SI5338A-B05147-GM

Overview

The SI5338A-B05147-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 features low phase jitter of 0.7 ps RMS typical, zero ppm frequency accuracy, and glitchless frequency adjustments. It operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V and is programmed via an I²C/SMBus interface.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four differential output drivers
• Low phase jitter of 0.7 ps RMS typical with true zero ppm frequency accuracy
• Highly-configurable output drivers supporting LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats
• Independent frequency increment/decrement feature for glitchless adjustments in 1 ppm steps

Applications

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

Procurement Notes

Verify the specific factory-programmed NVM configuration associated with the B05147 suffix against the target design requirements. Confirm that the QFN-24 package dimensions and thermal characteristics align with the PCB land pattern specifications provided in the datasheet.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single IC. Ensure the input reference source matches the supported formats (crystal, CMOS, SSTL/HSTL, or differential). Verify that the output voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) match the receiving device specifications.

Part Context

This part belongs to the Si5338 family of I²C-programmable clock generators. The 'A' indicates the high-performance variant capable of frequencies up to 710 MHz. The 'B05147' suffix denotes a specific factory-programmed configuration stored in non-volatile memory, while 'GM' indicates the 24-lead QFN package.

Replacement Considerations

Direct replacements within the same family include other Si5338 variants with different output frequency limits or programming options, such as the Si5338D or Si5338Q. Ensure the replacement part supports the required output frequencies and signal formats.
