SI5338N-B05684-GM

Overview

The SI5338N-B05684-GM is a programmable quad clock generator from Skyworks Solutions. It utilizes MultiSynth technology to synthesize any frequency on four independent output drivers with zero ppm precision. The device supports differential and single-ended outputs, including LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL formats. It operates from a single core supply of 1.8 V, 2.5 V, or 3.3 V and features low phase jitter of 0.7 ps RMS typical. Configuration is performed via an I2C/SMBus interface.

Feature Summary

• Four independent output drivers supporting any frequency synthesis up to 710 MHz
• Low phase jitter performance of 0.7 ps RMS typical
• Flexible input reference options including external crystals (8-30 MHz), CMOS, and differential inputs
• Independent output voltage configuration per driver (1.5, 1.8, 2.5, or 3.3 V)

Applications

• PCIe Gen 1/2/3/4 Common Clock and Gen 3 SRNS compliant systems
• Ethernet switch and router timing
• Processor and FPGA clocking
• Broadcast video/audio timing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm pinout compatibility and factory programming settings. Ensure the I2C pull-up voltage levels match the system requirements for standard or fast mode operation.

Selection Notes

Select this component when multiple independent clock frequencies are required from a single package. Verify that the desired output signal formats (LVPECL, LVDS, etc.) and frequencies fall within the supported ranges defined in the electrical specifications table.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The family is characterized by its ability to replace multiple discrete crystal oscillators with a single flexible timing solution, reducing board space and power consumption.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the Si5338 series. Verify that any substitute part supports the same output configurations and jitter requirements.
