The DSC1001AL2-029.4912T is a Microchip MEMS-based XO (Standard) oscillator delivering a 29.4912 MHz CMOS output. It is AEC-Q100 qualified, meaning it meets the automotive reliability and temperature stress requirements for under-hood and cabin electronics. Operating from -40°C to 105°C, it holds ±25ppm frequency stability across the full range — enough margin for CAN-FD, Ethernet, and sensor interfaces that cannot tolerate clock drift. Supply current is 7.2mA max, and the standby (power-down) function drops it to 15µA, useful for battery-backed modules that sleep between ignition cycles.

4-SMD package and board fit
Housed in a 4-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm. The exposed pad helps thermal transfer in high-temperature automotive environments — ensure the PCB landing pattern matches the datasheet recommendation for solder joint reliability. Supply voltage range is 1.8V to 3.3V, covering common core and I/O rails without an external regulator.
