The DSC1001DI5-002.0000T is a 2 MHz MEMS-based oscillator from Microchip's DSC1001 series, qualified to AEC-Q100 — the automotive IC reliability standard.
Tight stability across temperature and voltage
For a CAN bus node running at 2 MHz, that margin keeps the bit timing within the 1.5% tolerance the controller expects, even when the battery voltage sags during cranking.
Standby power-down for battery-conscious designs
In a telematics unit that sleeps between ignition cycles, the oscillator's own draw becomes negligible against the module's total sleep budget.
