4 MHz MEMS XO with AEC-Q100 and standby
The DSC1001CE1-004.0000 is a 4 MHz MEMS-based standard oscillator (XO) with CMOS output, rated across a 1.8V to 3.3V supply range and ±50 ppm frequency stability. Its AEC-Q100 qualification means this part has passed automotive-grade reliability stress — suitable for under-hood or cabin electronics where temperature cycling and vibration exceed commercial limits. The standby (power-down) function drops supply current to 15 µA max when disabled, letting the oscillator share a rail with a microcontroller that sleeps between wake events without draining the battery.
Supply range and power budget
Operating from 1.8V to 3.3V, this XO covers 1.8V logic, 2.5V I/O, and 3.3V system rails without a separate regulator — one less BOM line for mixed-voltage boards. Active current is 6.3 mA max at 4 MHz; the real power-saving edge is the 15 µA standby current, which keeps the oscillator off the thermal budget when the system is idle.
Housed in a 4-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, it fits tight PCB profiles and reflow processes common in automotive modules. The -20°C to 70°C operating range is commercial grade — adequate for cabin electronics and indoor equipment, but not for extended industrial or engine-bay ambient without additional qualification.
Listed as Active by Microchip Technology — this is a current-production part suitable for new designs and ongoing BOM replenishment. Sourced through independent distribution; quoted to order against the BOM quantity.
