12 MHz MEMS XO for automotive clock trees
The DSC6001JE2B-012.0000 is a 12 MHz fixed-frequency MEMS-based oscillator from Microchip's DSC60XXB series, delivering a CMOS output over a 1.8V to 3.3V supply range. AEC-Q100 qualification means this part is validated for automotive temperature and reliability stress profiles — it fits under-hood and cabin electronics where quartz oscillators might drift under vibration. The ±25 ppm frequency stability across -20°C to +70°C keeps timing margins tight for CAN, LIN, or sensor-sampling clocks without external compensation.
Package and footprint for board layout
Housed in a 4-VLGA package measuring 2.50 mm x 2.00 mm with a seated height of 0.89 mm, this oscillator occupies roughly the same PCB area as a 2012-size passive component — useful for space-constrained ECU or sensor-module layouts. The enable/disable function lets the system gate the clock output without a separate load switch, reducing component count on the rail.
Microchip lists the DSC6001JE2B-012.0000 as Active — no last-time-buy window, no PCN-driven urgency. It remains a viable choice for both new designs and production replenishment.
