12 MHz MEMS XO with AEC-Q100 qualification
The DSC6003JI1B-012.0000T is a 12 MHz XO (Standard) from Microchip's DSC60XXB series, delivering a CMOS output from a MEMS resonator. Its AEC-Q100 rating means this oscillator has passed the automotive-grade reliability stress and temperature qualification — it is not merely 'automotive-capable'; it carries the documented qualification an OEM auditor expects. The Enable/Disable function lets the system shut down the output for low-power sleep modes without removing the supply rail — a common requirement in battery-backed automotive ECUs.
Temperature range and supply flexibility
The supply voltage span of 1.8V to 3.3V means the same part can run from a 1.8-V core rail or a 3.3-V I/O rail, reducing BOM line count across board variants. Frequency stability is ±50 ppm, which keeps the clock edge timing within the window for CAN, LIN, or Ethernet physical-layer interfaces without external trimming.
