Product details

HCSL output for PCIe and high-speed serial clocks

The DSC1104CI1-027.0000: This oscillator delivers a 27 MHz HCSL (High-Speed Current Steering Logic) output — the standard reference clock format for PCIe Gen 1 through Gen 4, as well as SATA and USB 3.x. The 42 mA max supply current supports the 0.9V peak-to-peak swing into a 50-Ω differential termination without an external level shifter.

Industrial temperature range for outdoor and engine-bay use

The MEMS resonator survives the 50 g shock and 10–2000 Hz vibration profile typical of these environments — a quartz crystal would require a separate shock mount.

Wide supply voltage and standby power-down

The 2.25V to 3.6V supply range covers both 2.5V and 3.3V logic rails without a dedicated regulator — a single BOM line works across two voltage domains.

Frequently asked questions

What is the output type of DSC1104CI1-027.0000?

HCSL (High-Speed Current Steering Logic) — the standard reference clock format for PCIe and SATA interfaces. The differential swing is 0.9V peak-to-peak into a 50-Ω termination.
