The DSC1033DI2-027.0000T: Unlike a quartz crystal oscillator, the MEMS resonator is inherently more resistant to vibration and shock, and the device integrates the resonator and oscillator circuitry in a single 2.50 mm x 2.00 mm 4-SMD no-lead package.
Yes — the standby function disables the output and drops current consumption to 1 µA maximum, enabling power gating in portable or intermittently operated systems.
MEMS oscillators use a silicon micro-electromechanical resonator instead of a quartz crystal. They offer better resistance to shock and vibration, faster start-up, and often integrate features like standby mode, but the frequency stability (±25 ppm here) is comparable to quartz.
