SI5338N-B05066-GMR

Overview

The SI5338N-B05066-GMR is a programmable quad clock generator manufactured by 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, accommodating formats such as LVPECL, LVDS, HCSL, CMOS, SSTL, and HSTL. 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 at 1.5, 1.8, 2.5, or 3.3 V

Applications

• PCIe Gen 1/2/3/4 common clock and 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 official documentation to confirm pin assignments and factory programming configurations. Ensure compatibility with the required I2C bus voltage levels and check for moisture sensitivity handling requirements during storage and assembly.

Selection Notes

Select this component when multiple distinct clock frequencies are required from a single package. Confirm that the desired output signal formats (LVPECL, LVDS, etc.) match the available driver capabilities. Verify that the input reference source aligns with the supported frequency ranges for crystal or digital inputs.

Part Context

This part belongs to the Si5338 family of high-performance clock generators. The family is designed to replace multiple discrete oscillators in complex electronic systems. The specific model indicates a pre-programmed configuration variant within the broader Si5338 product line.

Replacement Considerations

Direct replacements must be sought within the Si5338 family. Verify that alternative part numbers support the same output count, frequency range, and package type (24-QFN). Cross-reference electrical specifications to ensure jitter and power consumption requirements are met.
