250 MHz LVDS clock from a MEMS resonator
The DSC1123CI2-250.0000 is a MEMS-based oscillator (XO) that delivers a 250 MHz LVDS output — a differential signal that rejects common-mode noise and keeps jitter low over long PCB traces, which is why you see it on high-speed serial links like Gigabit Ethernet or FPGA reference clocks.
The 2.25V–3.63V supply range means this one part covers both 2.5V and 3.3V logic rails — no need to stock separate voltage variants for different board designs. For under-hood applications that see 105°C+ ambient, check the DSC1123 family's higher-grade siblings.
Enable/Disable function and package
Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm — the same footprint as standard quartz oscillators, so a board designed for a 3.2x2.5 mm can accepts this MEMS part without a layout change.
Listed as Active — Microchip continues to manufacture this order code, and it remains open for new designs.
