What the 50 MHz and AEC-Q100 mean for your BOM
The DSC6101HA3B-050.0000T: That stability matters when the clock drives a CAN-FD or Ethernet PHY in an engine-bay ECU — the ppm budget stays tight even as the junction temperature swings. AEC-Q100 qualification (Grade 1) certifies the part for automotive stress profiles — 125°C ambient operation, high-temperature operating life, and temperature cycling per the AEC-Q100 test suite. This is the temperature grade for under-hood or transmission-mounted electronics, not just cabin infotainment.
Maximum current draw is 3 mA typical at 50 MHz. For a multi-oscillator design (e.g., MCU + Ethernet + USB), the combined budget stays under 15 mA — negligible against the rest of the power rail.
The small footprint suits space-constrained automotive modules like camera ECUs or radar sensor boards where every mm² is allocated.
