SI5338D-A-GM

Overview

The Skyworks SI5338D-A-GM is a programmable quad clock generator 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 from a single core supply of 1.8 V, 2.5 V, or 3.3 V with a typical current consumption of 45 mA. It features low phase jitter of 0.7 ps RMS typ, flexible input references up to 710 MHz, and glitchless frequency adjustments via I2C/SMBus interface.

Feature Summary

• MultiSynth technology enables independent, any-frequency synthesis on four output drivers with 0 ppm precision.
• Supports diverse output formats: LVPECL/LVDS (up to 710 MHz), HCSL (up to 250 MHz), CMOS (up to 200 MHz), and SSTL/HSTL (up to 350 MHz).
• Low phase jitter performance of 0.7 ps RMS typical value.
• Glitchless frequency adjustment in 1 ppm steps and independent phase adjustment with <20 ps accuracy.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'A' against the manufacturer's latest datasheet revision 1.6 to confirm pinout compatibility and electrical characteristics. Ensure the I2C pull-up voltage requirements match the system design, as register configuration may be needed for voltages below 2.5 V.

Selection Notes

Select this component when replacing multiple crystal oscillators with a single programmable source. Verify that the required output frequencies fall within the supported ranges for the chosen signal format. Confirm that the system can accommodate the 4x4 mm QFN-24 package dimensions and thermal requirements.

Part Context

The SI5338 series includes variants such as SI5338B, C, D, E, F, G, and Q. The 'D' suffix typically denotes specific factory programming or configuration parameters. All variants share the same functional architecture and package outline but differ in pre-programmed frequencies or specific feature sets defined by the manufacturer.
