The DSC1018DI2-006.0000 is a MEMS-based XO (Standard) that outputs a fixed 6 MHz CMOS clock from a 1.8V supply rail.
Frequency stability and temperature range
For a 6 MHz carrier, that is a maximum drift of ±150 Hz — tight enough for UART baud-rate generation and general-purpose clocking without external trim components.
Housed in a 4-SMD, no-lead package measuring 0.098" × 0.079" (2.50 mm × 2.00 mm) with a seated height of 0.035" (0.90 mm).
