The DSC1001CL1-100.0000T is a 100 MHz MEMS-based XO with CMOS output, rated across -40°C to 105°C and qualified to AEC-Q100 — the temperature range and automotive grade mean it can sit on an engine-control or transmission ECU board without derating concerns. Frequency stability is ±50 ppm, which covers the combined effects of temperature, supply variation, and aging — tight enough for 100BASE-T1 or CAN-FD reference clocks where the link budget is measured in nanoseconds.
The supply voltage range is 1.8V to 3.3V, so the same part works across a 3.3V I/O bank or a 1.8V core rail without a secondary regulator or level translator.
Product status is Active — no EOL notice, no last-time-buy window.
