Hello Cheyi,

I'm not sure what you mean by frequency calculator. Do you have an example part number? You can check out the timer devices such as LM555.

Regards,
Hao

It's similar LM2917. For example, ADC capture the 60Hz sinewave and calculate, and send the result=60Hz to MCU via I2C or SPI. MCU will show the result on interface.

Hi Cheyi,

I'm afraid that we don't have similar devices in our product line. Could you post a new question starting with LM2917? That way it will be categorized into the team that supports those parts.

Regards,
Hao
