SI5330C-A00208-GM

Clock Buffers, Drivers Overview

The Si5330C-A00208-GM is a low-jitter, low-skew clock buffer and level translator manufactured by Skyworks Solutions Inc. It accepts differential input signals and generates four HCSL output clocks within a frequency range of 5 to 250 MHz. The device operates with a single core supply voltage of 1.8 V, 2.5 V, or 3.3 V, while the output driver supply voltage is independently set to 2.5 V for this specific part number. Key electrical characteristics include a typical additive phase jitter of 150 fs RMS (12 kHz–20 MHz), an output-to-output skew of 100 ps, and a typical propagation delay of 2.5 ns. It is housed in a 24-lead, 4 x 4 mm QFN package.

Clock Buffers, Drivers Feature Summary

• Generates four differential HCSL outputs from a differential input
• Frequency range of 5 to 250 MHz
• Typical additive jitter of 150 fs RMS
• Output-output skew of 100 ps

Clock Buffers, Drivers Applications

• High Speed Clock Distribution
• Ethernet Switch/Router
• PCI Express 2.0/3.0

Clock Buffers, Drivers Procurement Notes

Verify the manufacturer designation as Skyworks Solutions Inc. on the final component marking, noting that the original datasheet lists Silicon Laboratories Inc. Confirm the ordering suffix matches the required HCSL output format and 2.5 V output supply voltage configuration. Check for current availability status as distribution channels may vary.

Clock Buffers, Drivers Selection Notes

Select this part when a differential input clock needs to be fan-out buffered into four HCSL signals. Ensure the system requires a 2.5 V output driver supply voltage. Verify that the maximum operating frequency of 250 MHz meets the design requirements, as higher frequencies are not supported for the HCSL output format.

Clock Buffers, Drivers Part Context

This component belongs to the Si5330 family of low-jitter clock buffers. The 'C' suffix indicates the HCSL output format variant. Other variants in the series support LVPECL, LVDS, CMOS, SSTL, and HSTL formats with different input/output configurations.

Clock Buffers, Drivers Replacement Considerations

Other Si5330 variants such as Si5330C-A00207-GM (3.3 V HCSL) or Si5330C-A00209-GM (1.8 V HCSL) share the same functional block but differ in output supply voltage requirements. Direct pin-compatible replacements must match the 2.5 V output supply specification.
