SI5338A-B05430-GM

Overview

The SI5338A-B05430-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 formats 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 such as external crystals (8–30 MHz), CMOS (up to 200 MHz), or differential inputs (up to 710 MHz). Configuration is performed via an I²C/SMBus interface.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four output drivers with 0 ppm precision.
• Low phase jitter performance of 0.7 ps RMS typical across various output formats.
• Highly configurable output drivers supporting up to four differential outputs, eight single-ended outputs, or mixed configurations.
• Independent frequency increment/decrement feature allows 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 configuration associated with the B05430 suffix against the target design requirements. Confirm that the QFN-24 package dimensions and thermal characteristics align with the PCB layout constraints. Ensure the I²C pull-up voltages match the system bus specifications for reliable communication.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single IC. Ensure the desired output voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) are supported by the individual driver supplies. Verify that the input reference source matches the supported frequency ranges for crystal, CMOS, or differential inputs.
