SI5338C-B05004-GM

Overview

The Skyworks SI5338C-B05004-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 flexible input references, including differential inputs up to 710 MHz and single-ended CMOS inputs up to 200 MHz. Output formats include LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL, with frequencies ranging from 0.16 MHz to 710 MHz depending on the format. It operates from a 1.8 V, 2.5 V, or 3.3 V core supply with a typical current of 45 mA.

Feature Summary

• Four independent output drivers supporting any frequency synthesis with 0 ppm accuracy
• Low phase jitter performance of 0.7 ps RMS typical
• Flexible input reference options: external crystal (8-30 MHz), CMOS (5-200 MHz), SSTL/HSTL (5-350 MHz), and differential (5-710 MHz)
• Configurable spread spectrum generation with adjustable deviation and modulation rate

Applications

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

Procurement Notes

Verify the specific factory configuration code B05004 against the official Skyworks ordering guide to ensure correct pre-programmed register settings. Confirm package type and temperature range specifications match the design requirements before procurement.

Selection Notes

Select this component for designs requiring multiple independent clock frequencies from a single IC. Ensure the required output voltage levels (1.5V, 1.8V, 2.5V, or 3.3V) are supported by the target load. Verify that the input source matches one of the supported formats and frequency ranges.

Part Context

This part belongs to the Si5338 family of I2C-programmable any-frequency, any-output quad clock generators. It replaces discrete oscillators and frequency translators in high-performance digital systems.

Replacement Considerations

Direct pin-to-pin replacements within the same family require identical factory programming codes. Verify compatibility with ClockBuilder Pro software configurations when substituting.
