The DSC1001CI2-024.9600T is a MEMS-based XO (Standard) from Microchip Technology that outputs a 24.96 MHz CMOS clock with ±25 ppm frequency stability over its full -40°C to 85°C range — no quartz aging or shock sensitivity to budget for. For an ECU clock or a CAN transceiver reference, this is the part that ships with a PPAP package.
The 1.7V to 3.6V supply range lets it run directly off a 1.8V core rail, a 2.5V I/O bank, or a 3.3V system bus — no extra regulator or level translator needed on the clock line. For a battery-powered sensor that wakes every few seconds to transmit, the standby current is well below the system sleep budget.
Housed in a 4-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the footprint is small enough for a space-constrained PCB under a display or battery pack. The VDFN has exposed pads on the bottom — a standard reflow profile handles it, and a fine-tip iron can hand-solder it with careful technique.
