SI5338A-B06038-GM

Overview

The SI5338A-B06038-GM is a programmable quad clock generator utilizing MultiSynth technology. It synthesizes four independent output clocks with 0 ppm frequency accuracy and typical phase jitter of 0.7 ps RMS. The device supports differential (LVPECL, LVDS, CML) and single-ended (CMOS, HCSL, SSTL, HSTL) formats across frequencies up to 710 MHz. It operates on a single core supply of 1.8 V, 2.5 V, or 3.3 V, with configurable output voltages per driver. Configuration is performed via an I2C/SMBus interface.

Feature Summary

• MultiSynth™ technology enables independent, any-frequency synthesis on four output drivers with true zero ppm accuracy.
• Low phase jitter performance of 0.7 ps RMS typ, compliant with PCIe Gen 1/2/3/4 Common Clock standards.
• Flexible input reference options including external crystals (8–30 MHz), CMOS, SSTL/HSTL, and differential inputs up to 710 MHz.
• Highly configurable outputs supporting up to four differential or eight single-ended signals with independent voltage levels.

Applications

• PCIe Gen 1/2/3/4 common clock generation
• 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-programmed configuration associated with the B06038 suffix against the target design requirements. Confirm that the QFN-24 package dimensions align with the recommended PCB land pattern. Ensure ESD handling procedures are followed due to the device's sensitivity ratings.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single IC. Verify that the input source matches the supported formats (crystal, CMOS, or differential). Check that the required output signal types and voltage levels are compatible with the available driver configurations.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces discrete crystal oscillators by providing flexible frequency synthesis. The device integrates NVM for storing custom programming data, allowing it to function as a standalone clock source after initial configuration.

Replacement Considerations

Direct pin-to-pin replacements within the same family include other Si5338 variants with different factory-programmed frequencies. Ensure the replacement part supports the required output frequencies and signal formats specified in the application design.
