SI5338B-B06143-GM

Overview

The SI5338B-B06143-GM is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes any frequency on four independent output drivers with zero ppm precision. The device supports differential and single-ended outputs including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. Maximum input frequencies reach 710 MHz for differential inputs and 200 MHz for CMOS. Output frequencies range from 0.16 to 710 MHz depending on the format. It operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V with typical current consumption of 45 mA.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers with true zero ppm accuracy.
• Low phase jitter performance of 0.7 ps RMS typical.
• Highly configurable output drivers supporting up to four differential, eight single-ended, or mixed configurations.
• Independent frequency increment/decrement and phase adjustment features with glitchless adjustments.

Applications

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

Procurement Notes

Verify the specific factory programming code B06143 against the official Skyworks ordering guide to confirm the exact synthesized frequencies and pinout configuration. Ensure I2C pull-up voltages are compatible with the selected VDDI2C level, as register modifications may be required for voltages below 2.5 V.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single package. Verify that the target output formats (LVPECL, LVDS, etc.) match the voltage requirements of the receiving devices. Confirm that the input reference source meets the specified frequency and swing requirements for the chosen input pins.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The 'B' suffix indicates a specific factory-programmed variant with predefined frequencies, distinguishing it from blank or user-programmable versions. It replaces discrete crystal oscillators in complex digital systems.

Replacement Considerations

Direct functional replacements within the same family include other Si5338 variants such as SI5338A or SI5338Q, provided the specific frequency plan matches the application requirements. Pin compatibility is maintained across the QFN-24 package variants.
