Product details

100 MHz MEMS oscillator for PCIe clock trees

Supply voltage spans 2.25V to 3.6V, so it runs from a 2.5V or 3.3V rail without a separate regulator.

Frequency stability of ±25 ppm keeps the PCIe reference within the total budget for Gen1/Gen2 links, with margin for the PLL jitter and board-level spread.

This is a design-in grade part — no last-time-buy window to manage. The DSC1124 base number covers the full series; the suffix CI2-100.0000T specifies the 100 MHz frequency, ±25 ppm stability, and industrial temperature range.

Frequently asked questions

What is the output signal type of the DSC1124CI2-100.0000T?

The output is HCSL (High-Speed Current Steering Logic), the standard for PCIe reference clocks. It drives the clock tree directly without a level translator.
