SI5338A-B06088-GM

Overview

The SI5338A-B06088-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 including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. The device operates with a core supply of 1.8 V, 2.5 V, or 3.3 V and features low phase jitter of 0.7 ps RMS typical. It accepts flexible input references ranging from external crystals (8–30 MHz) to differential inputs up to 710 MHz. Configuration is managed via an I²C/SMBus interface.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis with true zero ppm accuracy on four outputs.
• Low phase jitter performance of 0.7 ps RMS typical, compliant with PCIe Gen 1/2/3/4 Common Clock standards.
• Highly configurable output drivers supporting LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats with independent voltage levels.
• Flexible input reference options including external crystals, CMOS, SSTL/HSTL, and differential signals up to 710 MHz.

Applications

• Ethernet switch/router clocking
• PCIe Gen1/2/3/4 common clock generation
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards

Procurement Notes

Verify the specific factory-programmed configuration associated with the suffix B06088 against the system requirements using Skyworks ClockBuilder Pro software. Confirm that the QFN-24 package dimensions and thermal characteristics align with the PCB land pattern recommendations in the datasheet. Ensure I²C pull-up voltages are compatible with the selected core supply voltage.

Selection Notes

Select this component when multiple independent clock frequencies with high precision are required from a single IC. Ensure the target output formats (LVPECL, LVDS, etc.) and frequencies fall within the specified ranges for each driver. Verify that the input reference source matches one of the supported types (crystal, CMOS, or differential). Consider the 45 mA typical core supply current for power budget calculations.

Part Context

This part belongs to the Si5338 family of I²C-programmable clock generators. The 'A' designation typically indicates a specific performance grade or feature set within the series, while 'B06088' denotes a unique factory-programmed configuration stored in non-volatile memory. The '-GM' suffix indicates the 24-lead QFN package and tape-and-reel shipping format.

Replacement Considerations

Direct pin-to-pin replacements within the Si5338 family may exist but require verification of the programmed configuration. Other Skyworks Si53xx series devices offer similar functionality but may differ in output count, jitter performance, or input flexibility. Consult the official cross-reference guide for validated substitutes.
