SI5338A-B05696-GMR

Overview

The SI5338A-B05696-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 input and output frequencies reach 710 MHz for differential signals. It operates from a single core supply of 1.8 V, 2.5 V, or 3.3 V with typical current consumption of 45 mA. Jitter performance is characterized by 0.7 ps RMS random jitter. Configuration is managed 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 of 0.7 ps RMS typ, compliant with PCIe Gen 1/2/3/4 Common Clock standards.
• Highly configurable outputs support LVPECL, LVDS, CML, HCSL, CMOS, SSTL, and HSTL formats.
• Independent glitchless frequency adjustment in 1 ppm steps and phase adjustment with <20 ps accuracy.

Applications

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

Procurement Notes

Verify the specific ordering suffix B05696 against official Skyworks documentation to confirm factory-programmed frequency and format configurations. Confirm package availability and moisture sensitivity level requirements prior to assembly planning.

Selection Notes

Select this component when independent frequency synthesis across multiple outputs is required without external crystal oscillators. Ensure the target application voltage matches the available 1.8 V, 2.5 V, or 3.3 V core supply options. Validate that the required output signal formats are supported by the specific pin configuration.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. It replaces discrete crystal oscillators and buffers. The device integrates a PLL and four MultiSynth dividers within a compact 4x4 mm QFN-24 package.

Replacement Considerations

Direct replacements require matching the 24-QFN package and I2C interface. Verify that substitute devices support the same maximum input/output frequencies and jitter specifications for the intended application.
