Product details

49.152 MHz MEMS XO – AEC-Q100 qualified

The DSC1001DI2-049.1520 is a 49.152 MHz standard XO (Standard) oscillator built on a MEMS resonator, delivering CMOS output in a 4-SMD, No Lead package. It carries AEC-Q100 qualification, making it suitable for automotive-grade timing applications where reliability under temperature and vibration is specified.

Frequency stability and supply range

Supply voltage spans 1.8V to 3.3V, so the same oscillator can serve a 1.8V MCU core and a 3.3V peripheral bus without a separate rail regulator.

Frequently asked questions

What is the frequency tolerance of the DSC1001DI2-049.1520?

The frequency stability is ±25 ppm over the operating temperature range. This is the total variation including initial accuracy, temperature drift, and aging over the rated life.

Is the DSC1001DI2-049.1520 AEC-Q100 qualified?

Yes, it carries AEC-Q100 ratings, which means it has passed automotive-grade stress tests including temperature cycling, ESD, and latch-up. It is suitable for under-hood and cabin electronics.

Is the DSC1001DI2-049.1520 compatible with standard CMOS logic?

Yes, the output is CMOS, so it drives standard CMOS logic inputs directly. No level translation is needed between the oscillator and the downstream clock receiver.

What is the standby current for the DSC1001DI2-049.1520?

When the standby (Power Down) function is active, the maximum supply current is 15 µA. This allows the oscillator to be disabled during system sleep without draining the battery.
