1.8432 MHz MEMS XO with AEC-Q100 qualification
The DSC1001DL1-001.8432: Rated AEC-Q100, this part is qualified for automotive under-hood and chassis-domain applications — the same qualification covers factory-floor and outdoor telecom gear without additional reliability screening. The MEMS resonator core gives it better shock and vibration immunity than a quartz crystal, and it starts up faster — relevant for engine-control modules and portable instruments that cycle power frequently.
Supply flexibility and power-down standby
Supply voltage spans 1.8V to 3.3V, so the same oscillator can clock a 1.8V MCU core and a 3.3V peripheral bus without a level translator — one line item covers both rails. A standby (power-down) function drops the supply current to 15 µA max, letting the system shut the clock off during sleep modes and meet low-power targets without a separate enable circuit. Active current draw is 6.3 mA max at the highest supply voltage — negligible for most automotive and industrial loads, but worth noting for battery-powered designs where every milliamp counts.
Package and board-fit considerations
Housed in a 4-SMD, no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits tight PCB layouts in ECU and sensor modules.
