SI5338C-B05960-GMR

Overview

The SI5338C-B05960-GMR 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

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm factory programming parameters. The GMR suffix indicates tape-and-reel packaging. Ensure compatibility with the required I2C bus voltage levels for system integration.

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.) match the available driver configurations. Confirm that the input reference frequency falls within the supported ranges for the chosen mode.

Part Context

This part belongs to the Si5338 family of I2C-programmable clock generators. The family is designed to replace multiple discrete crystal oscillators in high-performance digital systems. The specific model variant defines the pre-programmed frequency and format settings stored in the internal memory.

Replacement Considerations

Direct pin-to-pin replacements within the same family include other Si5338 variants with different factory presets. Verify that the replacement part supports the required output frequencies and signal formats before substitution.
