Its maximum output frequency is 600kHz. That is a high frequency. For slower microcontrollers it can be lowered. For example with a internal divider in the sensor of 50 the maximum output frequency is 12kHz.
Long time ago, some sensors would output a frequency. That was the only way to get accurate data to a microcontroller. However, since 1982 there is the I2C bus to communicate with sensors. You should not use this sensor. It is a whole lot of trouble for nothing.
