NXQ1TXH5 with external clock

[user_159357]

Hi All,

does anyone have an idea of how to connect an external clock signal to the NXQ1TXH5?

Do I connect the clock to the XTAL_IN an leave the XTAL_OUT floating?

I have seen solutions where it is the other way around...

Best regards

Hi Benedict,

Here is the answer:

It is very important to have a very stable oscillator signal to make the wireless charger work correctly.

So if you connect an external clock signal, then you must be very sure that this oscillator signal has a very stable frequency of 32768Hz.

The external clock signal should be connected to the XTAL_IN pin and the high level must be between 1.5 and 1.8V.

The low level must be between 0 and 0.3V. The XTAL_OUT pin must be left floating.

Let us know if you have any other questions.

Best regards,

Tomas

Hi Benedict,

This is just to let you know that your question has been forwarded to the designer of the oscillator block. I will update this thread as soon as I have his answer.

Thanks for your patience.
