Hi Team,
I understand that DS25BR120 can support AC coupling.
(I referred to INPUT INTERFACING of page7 of datasheet .)
If yes, could you please let us know the bias voltage of input pins(IN+,IN-)?
[Background]
Our customer confirmed input pin voltage at the following measurement environment.
At the result, there is a voltage fluctuation(±100mV) around 0V so they can’t find bias voltage.
They concern that this voltage doesn't meet " VCMR=0.05 to Vcc-0.05".
[Measurement environment]
Input source -> AC coupling(0.1uF)-> DS25BR120* -> AC coupling(0.1uF)-> receiver(100ohm termination)
* Then, they confirmed the waveform(voltage) with the differential input set to single-ended.
Regards,
Hide
