I looked into DC1931B which is the evaluation board for LTM9013.
In DC1931B, REF PIN is connected to VDD/2(=0.9V).
On the other hand, in the datasheet Page4, input voltage of Demodulator Adjust Input(REF) voltage is defined as follows.
0.4v(min) 0.5V(typ) 0.7V(max).
where does this discripancy come from?
