The LVDS output swings differentially, which keeps the 250 MHz edge clean across a short PCB trace to the FPGA or SerDes receiver.
The DSC1123 series is Microchip's current MEMS oscillator family; the 250 MHz LVDS variant is a standard catalog line.
Yes, it carries an AEC-Q100 rating, making it suitable for automotive applications where the ambient temperature stays within -40°C to 85°C — under-hood or cabin-mount.
The base number DSC1123CI2 identifies the series, package, and temperature grade. The full order code adds the specific frequency (250.0000 MHz) and the tape-and-reel packaging suffix (T). All other ratings — LVDS output, ±25 ppm stability, AEC-Q100 — are common to the base number.
