Housed in a 4-SMD, no-lead exposed-pad package measuring 7.00 mm x 5.00 mm x 0.90 mm — the exposed pad helps thermal conduction but also means the part sits flush against the board; a hot-air rework station with a nozzle that covers the full body works best, and the pad needs a good solder paste stencil aperture to avoid voids.
The DSC1001AI5-018.4320T outputs a fixed 18.432 MHz CMOS clock signal.
It operates from a 1.8V to 3.3V supply range, covering common digital rails without an extra regulator.
Yes, it is AEC-Q100 rated, making it suitable for automotive applications requiring validated reliability under temperature and vibration stress.
No direct pin-compatible replacement is listed by the manufacturer. The DSC1001 series includes other frequency variants, but for 18.432 MHz this is the active order code.
