The DSC1001CE2-037.1250T is an active-production MEMS-based XO from Microchip Technology's DSC1001 series, delivering a fixed 37.125 MHz CMOS output. Its AEC-Q100 rating means it passed automotive-grade reliability stress — temperature cycling, ESD, and latch-up — so it can sit on an automotive PCB without a separate screening step.
Supply voltage spans 1.8V to 3.3V, so the same order code works across a 1.8V MCU bank or a 3.3V FPGA bank without a separate regulator tap.
Housed in a 4-SMD No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. Supplied on Tape & Reel, which is the expected format for automated assembly.
