75 MHz MEMS XO with AEC-Q100 — what it buys the design
The DSC1201CL1-75M00000T is a 75 MHz MEMS-based oscillator in the DSC12X1 series, delivering a CMOS output from a 2.5V to 3.3V supply rail. The AEC-Q100 rating means it has passed the automotive-grade stress and reliability tests — under-hood or cabin ambient up to +105°C is within its operating envelope.
Standby mode and supply current — battery-aware design
The Standby (Power Down) function drops the supply current to 5 µA max when the enable pin is pulled low, compared to 27 mA typical during active oscillation. For a module that spends most of its life asleep and wakes on a bus event, this idle current is low enough to ignore in the battery budget.
Package, footprint, and board integration
Housed in a 6-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the part is a drop-in for standard MEMS oscillator footprints. The surface-mount land pattern follows the JEDEC VDFN outline — no via-in-pad needed, but the centre thermal pad should be connected to the ground plane for best thermal and electrical performance.
