Product details

12.288 MHz MEMS oscillator with AEC-Q100 qualification

Its AEC-Q100 qualification makes it suitable for automotive applications where reliability under thermal and mechanical stress is required, such as infotainment, ADAS sensor clocks, or body controller timing. The standby function drops supply current to 15 µA max, enabling power gating in battery-backed or sleep-mode circuits without an external load switch.

Supply range and power budget

Operating from 1.8V to 3.3V, this oscillator can be powered directly from a 1.8V core rail or a 3.3V I/O rail, eliminating a dedicated regulator for the clock source. Maximum supply current is 6.3 mA during active operation — lower than many quartz-based oscillators at the same frequency, which helps keep the thermal budget tight in dense PCB layouts.

Package and footprint compatibility

Housed in a 4-SMD, No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm, the DSC1001CI1-012.2880 uses the same footprint as standard quartz oscillators, so it can be a drop-in replacement without a board layout change.

Frequently asked questions

Is DSC1001CI1-012.2880 AEC-Q100 qualified?

Yes, the DSC1001CI1-012.2880 is AEC-Q100 qualified, which means it has passed automotive-grade reliability testing including temperature cycling, ESD, and latch-up. This qualifies it for use in under-hood and cabin electronics where the ambient temperature can reach 85°C.

Can DSC1001CI1-012.2880 replace a standard quartz oscillator?

Yes, in most cases. The DSC1001CI1-012.2880 uses a MEMS resonator instead of quartz, but it has the same 4-SMD, No Lead footprint and outputs a standard CMOS signal. The ±50 ppm stability is comparable to many quartz oscillators, and the wide supply range covers common voltages. The main difference is the standby pin — if your existing quartz oscillator does not have a standby function, you may need to leave the pin unconnected or tie it to Vdd.

What is the function of the standby pin on DSC1001CI1-012.2880?

The standby (Power Down) function disables the oscillator output and reduces current consumption to 15 µA max. When the standby pin is asserted, the output goes into a high-impedance state, and the internal MEMS resonator stops oscillating. This is useful for battery-powered devices that need to save power during sleep modes.
