SI5338A-B04519-GMR

Overview

The SI5338A-B04519-GMR 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 formats including LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL. Maximum output frequencies reach 710 MHz for differential outputs and 200 MHz for CMOS. It operates from a single core supply of 1.8 V, 2.5 V, or 3.3 V. Typical phase jitter is 0.7 ps RMS. Configuration is performed via an I2C/SMBus interface.

Feature Summary

• Low phase jitter of 0.7 ps RMS typical
• High precision synthesis allows true zero ppm frequency accuracy
• Flexible input reference supporting external crystals (8-30 MHz), CMOS, SSTL/HSTL, and differential inputs

Applications

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

Procurement Notes

Verify the specific B04519 factory configuration against the datasheet ordering information table to ensure correct output formats and frequencies. Confirm package type is 24-QFN and operating temperature range is -40 to +85 °C. Check RoHS compliance status in official documentation.

Selection Notes

Select this component when low jitter (<1 ps RMS) and flexible output voltage levels (1.5, 1.8, 2.5, or 3.3 V per driver) are required. Ensure input reference frequency matches supported ranges: 5-710 MHz for differential, up to 200 MHz for CMOS. Use ClockBuilder Pro software for configuration.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces multiple crystal oscillators by providing four independent clocks. The 'B' suffix typically denotes a specific factory-programmed configuration within the series.

Replacement Considerations

Consult the datasheet section on Device Errata and Ordering Information for confirmed substitutes. Verify pinout compatibility with the 24-QFN package if replacing older variants like the SI5338C.
