Product details

The DSC1001AI2-070.4550T: AEC-Q100 qualification means this oscillator is tested for automotive-grade reliability—under-hood temperature cycling, ESD, and extended life—making it suitable for engine control units, ADAS sensors, and infotainment modules.

Supply range and standby power-down

Operating from 1.8V to 3.3V, this oscillator spans the common logic rails used in automotive and industrial designs—no separate regulator needed when the core voltage shifts. Active current draw is 8.7 mA max at full speed, a reasonable budget for a 70 MHz clock tree in a mixed-signal system.

Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90 mm, this footprint matches the standard 7x5 ceramic oscillator land pattern.

Frequently asked questions

Is the DSC1001AI2-070.4550T AEC-Q100 qualified?

Yes, it carries AEC-Q100 qualification, meaning it is tested for automotive-grade reliability including temperature cycling, ESD, and extended life.

What is the output type of the DSC1001AI2-070.4550T?

The output is CMOS, a single-ended logic level compatible with most digital inputs.

What is the function of the Standby pin on the DSC1001AI2-070.4550T?

The Standby (Power Down) function disables the output and reduces supply current to 15 µA max, allowing the system to conserve power during sleep or key-off modes.

Is the DSC1001AI2-070.4550T RoHS compliant?

RoHS compliance is standard for the DSC1001 series; confirm the specific date code at RFQ.
