The 80 MHz frequency suits high-speed serial interfaces (Ethernet, PCIe reference clocks) and processor core timing where a quartz crystal would need a separate PLL to reach that rate.
In a battery-backed ECU or sensor module that spends most of its life asleep, this cuts the oscillator's draw from 16.6 mA to near-zero — the disable current is lower than the self-discharge of a typical coin cell.
Yes, the DSC1001DE3-080.0000 is rated AEC-Q100.
Functionally yes — it provides the same 80 MHz CMOS clock output as a quartz XO, but the MEMS resonator is more shock- and vibration-tolerant than a quartz crystal. The 4-VDFN package is a standard footprint, so it drops onto the same PCB pads as many quartz oscillators. However, the AEC-Q100 rating and the standby power-down feature are not available on most quartz parts.
The Standby (Power Down) function disables the oscillator output and reduces the supply current to 15 µA max. This is useful for battery-backed systems that need to preserve power during idle periods while keeping the oscillator ready to wake on a control signal.
