Product details

The MEMS resonator eliminates the quartz-crystal startup issues and vibration sensitivity that plague traditional oscillators in automotive environments. That covers under-hood and cabin modules where thermal cycling and mechanical shock are routine.

Standby mode and supply flexibility

The supply voltage range spans 1.8V to 3.3V, allowing the same oscillator to serve 1.8V-core MCUs and 3.3V peripheral buses without a level translator.

Package and footprint for production

Housed in a 4-SMD, no-lead exposed pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm.

Frequently asked questions

What is the frequency of DSC1001AI1-001.8432T?

The oscillator outputs a fixed 1.8432 MHz CMOS signal. This frequency is commonly used for UART baud-rate generation and low-speed MCU clocking.

Does DSC1001AI1-001.8432T have a standby mode?

Yes, the part includes a Standby (Power Down) function. When enabled, the supply current drops to 15 µA max, allowing the oscillator to be gated off during system sleep states.
