The DSC1001AE2-100.0000 is a 100 MHz MEMS-based oscillator (XO) from Microchip, delivering a CMOS output in a 4-SMD, no-lead exposed-pad package. The -20°C to +70°C operating range covers cabin and most under-hood ambient conditions, though the AEC-Q100 Grade 3 (or higher) rating means the die and package have passed the full automotive qualification flow.
The oscillator accepts a 1.8V to 3.3V supply rail, covering the three most common digital logic voltages without an external regulator. Maximum supply current is 8.7 mA at 100 MHz — a modest draw for a 100 MHz clock source.
