Product details

29.4912 MHz MEMS oscillator – why the ±50 ppm matters

The DSC1033CI1-029.4912: That ±50 ppm stability keeps the clock edge within a tight window over temperature – suitable for a UART baud-rate generator or a low-jitter reference in a sensor hub, but not a precision RF carrier. Supply is 3.3 V nominal; the oscillator draws 3 mA typical during active operation and drops to 1 µA in standby via the power-down function – a useful feature for battery-powered equipment that cycles between active and sleep states.

Package and footprint – 3.2 mm × 2.5 mm no-lead

Housed in a no-lead package measuring 3.20 mm × 2.50 mm with a seated height of 0.90 mm.
