SI5338E-A-GM

Overview

The SI5338E-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 synthesis of any frequency with 0 ppm precision on four outputs
• Supports diverse signal formats: LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL
• Low phase jitter performance of 0.7 ps RMS typical
• Glitchless frequency adjustment in 1 ppm steps and independent phase adjustment < 20 ps

Applications

• PCIe Gen 1/2/3/4 common clock and SRNS compliant systems
• Ethernet switch/router timing
• Processor and FPGA clocking
• Broadcast video/audio timing
• Telecom line cards and MSAN/DSLAM/PON

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type, temperature range, and shipping configuration. Ensure compatibility with ClockBuilder Pro software for programming. Confirm that the I2C pull-up voltage requirements align with the system design, particularly if operating below 2.5 V.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single IC to replace discrete oscillators. Verify that the required output voltage levels (1.5 V, 1.8 V, 2.5 V, or 3.3 V) match the load requirements. Ensure the input reference frequency falls within the supported ranges for the chosen format (e.g., up to 710 MHz for differential inputs).

Part Context

The SI5338 series belongs to Skyworks' MultiSynth family of clock generators. This specific model provides quad output capabilities in a compact 4x4 mm QFN-24 package. It is designed to reduce board space and BOM count by consolidating multiple oscillator functions into a single programmable device.
