Product details

MEMS oscillator for automotive and industrial timing

The DSC1121CI2-012.2880T: AEC-Q100 qualification means this part is screened for automotive-grade reliability — under-hood or cabin electronics that see thermal cycling and vibration can use it without a separate qualification step. The MEMS resonator is inherently more shock- and vibration-tolerant than a quartz crystal — a meaningful advantage in motor-drive or powertrain environments where crystal micro-cracking is a known failure mode.

Supply voltage and output drive

Operating from 2.25V to 3.6V, this oscillator spans the 2.5V and 3.3V logic rails common in automotive ECUs and industrial controllers — no extra regulator needed for the clock tree. Maximum supply current is 35 mA; the disable function drops it to 22 mA — useful for power-save modes in battery-backed or ignition-off domains.

Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, it fits tight-profile designs and standard reflow processes. The Enable/Disable pin lets a GPIO or power-management IC gate the output — no external load-switch or series FET needed to silence the clock during sleep.

This part is suitable for new designs and production builds without a forced migration timeline.
