Hello,
I am woriking with TDC1011 in a project where 1MHz ultrasonic transducers will be used to measure some media concentration.
However, at this point of the project I replase the ultrasonic signal by a 1MHz sine wave from a GFG-3015 generator. The point is that we are using the TDC1011 only for signal amplification. I mean that we don´t use it to measure the time of flight. We are only interested in the LNA and PGA amplifiers.
So looking to the datasheet, I write a 0x10 value in TOF_1 register focusing by the moment on the LNA (I don´t touch any other register). I see on the oscilloscope a 1MHz sine wave on RX pin, but however no signal is on LNOUT pin. What is going on?
Could someone tell me what am I missing?
Any help will be appreciated.
Thanks in advance.
