MEMS resonator avoids quartz startup and shock limits
Unlike quartz crystal oscillators, the MEMS resonator has no start-up time dependency on load capacitance and survives higher mechanical shock — relevant for portable or vibration-prone installations.
3.3V supply with 3 mA draw and 1 µA standby
Operating from a single 3.3V rail, the oscillator draws 3 mA (typ) maximum during active oscillation, and drops to 1 µA when the standby (power-down) function is asserted. The standby pin lets a system-level controller gate the clock tree during idle periods, cutting the oscillator's contribution to the sleep-mode power budget to negligible levels.
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), the DSC1033DI2-027.0000 fits into space-constrained designs where a larger quartz can would force a board respin.
