125.0032 MHz MEMS clock for automotive timing
The DSC1121AI5-125.0032T: The MEMS resonator eliminates the quartz-crystal cold-start drift and vibration sensitivity issues that plague traditional oscillators in engine-bay and chassis-mount applications. AEC-Q100 qualification means this part has passed the automotive-grade reliability stress tests — temperature cycling, biased humidity, and ESD — required for under-hood and cabin ECUs. The Enable/Disable function allows the output to be tri-stated, cutting supply current from 35 mA max to 22 mA max — useful for power-cycled subsystems or test modes where the clock must be gated without removing the supply.
There is no announced end-of-life or NRND notice, so the part is available for both new designs and ongoing production without a last-time-buy window. Sourced through independent distribution, this oscillator is quoted to order against the BOM quantity.
6-SMD package and footprint fit
The 6-SMD, No Lead Exposed Pad package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm. Surface-mount mounting suits automated pick-and-place assembly. The 35 mA max supply current is well within the capacity of a typical 3.3 V rail, so no additional bulk decoupling is needed beyond the standard 0.1 µF ceramic at the supply pin.
