The MEMS resonator gives it a start-up time under 5 ms, which beats a quartz crystal that can take 10–20 ms to stabilize at this frequency. ## Temperature grade and automotive qualification Rated -40°C to +125°C with AEC-Q100 qualification, this oscillator is specified for the full automotive temperature envelope — under-hood ECU, transmission controller, or cabin module. No derating needed at 125°C ambient. Frequency stability is ±20 ppm across the entire temperature range — tight enough for CAN-FD bit timing (which typically requires ±1.5% or ±15000 ppm) and well within LIN 2.2A specs. For precision applications like GPS or Ethernet, you would need a TCXO or OCXO. Four pins: VDD, GND, OUT, and OE (enable/disable). ## Sourcing and lifecycle posture Packaged in tube, not tape-and-reel — if your pick-and-place line expects reeled parts, request reel packaging at order time or plan a tube-to-reel transfer.","metaTitle":"DSC6043JA3B-127K000 MEMS XO, 127 kHz, AEC-Q100, Active","metaDescription":"Microchip DSC6043JA3B-127K000 MEMS oscillator, 127 kHz CMOS output, ±20 ppm stability, -40 to +125°C, AEC-Q100.
