Product details

114.285 MHz LVPECL MEMS oscillator for high-speed clock trees

The DSC1122BI2-114.2850T is a MEMS-based XO delivering a 114.285 MHz LVPECL output — a common frequency for 10GbE, Fibre Channel, and high-speed serial links where the differential pair keeps jitter below the link budget. Supply voltage spans 2.25V to 3.6V — the wide range lets it share a rail with 2.5V or 3.3V logic without a separate LDO, simplifying the power tree.

Supplied on Tape & Reel (TR) for automated pick-and-place; the 6-SMD, No Lead package (5.00mm x 3.20mm) is a standard footprint shared across the DSC1122 family, so a feeder change is the only line adjustment if swapping frequencies.

MEMS vs quartz — what the base resonator means for your build

Frequently asked questions

Where can I buy DSC1122BI2-114.2850T and what is the lead time?

The Tape & Reel packaging supports volume orders without a packaging change.

What is the closest pin-compatible alternative to DSC1122BI2-114.2850T in the DSC1122 family?

Any DSC1122 variant with the same 6-SMD footprint and LVPECL output is pin-compatible — only the frequency and stability grade differ. The base product number DSC1122 covers the whole family; confirm the specific frequency and ppm grade against your PLL's capture range before substituting.

Is DSC1122BI2-114.2850T suitable for outdoor or industrial environments?

The MEMS resonator also handles vibration better than quartz in these settings.
