Product details

MEMS oscillator for automotive-grade clock trees

The DSC1001DE1-074.2500 is a MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series, delivering a 74.25 MHz CMOS output with ±50 ppm frequency stability across its -20°C to +70°C operating range.

This makes the oscillator suitable for battery-backed or intermittent-duty modules where the clock tree must be gated during sleep to conserve energy.

Housed in a 4-SMD, no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, the footprint is compatible with standard reflow soldering and requires no special via-in-pad treatment. Surface-mount mounting aligns with automated assembly lines; the compact size suits space-constrained PCBs in camera modules, infotainment head units, or ADAS sensor boards.

Frequently asked questions

What is the standby power-down function of DSC1001DE1-074.2500?

The standby function disables the oscillator output and internal bias circuitry, reducing supply current from 8.7 mA active to 15 µA max in standby. The output enters a high-impedance state; the part resumes normal operation when the standby pin is de-asserted, with no start-up time penalty typical of quartz oscillators.

Is DSC1001DE1-074.2500 AEC-Q100 qualified?

Yes, the device carries AEC-Q100 ratings, meaning it has passed automotive-grade stress tests including temperature cycling, ESD, and latch-up. The -20°C to +70°C operating range covers passenger-cabin and most under-hood applications, though not extended -40°C extremes.
