The DSC1001AL5-018.4320 is a standard XO built around a MEMS resonator rather than a quartz crystal, outputting a 18.432 MHz CMOS clock from a 1.8V to 3.3V supply rail.
Housed in a 4-SMD no-lead exposed pad package measuring 7.00 mm × 5.00 mm with a seated height of 0.90 mm — a standard footprint that matches many quartz oscillator land patterns, so a direct layout swap is feasible without a board spin.
