Hello team,
My customer want to know the S-parameter value of VOD_0 setting.
It doesn't seem there is that model.
what s-parameter model should we use for VOD_0 ?
Thanks,
Shoo

The s-parameter model is available at this link, https://www.ti.com/product/SN65LVCP1414#design-development.
The s-parameter was done through actual lab measurement.
With the lab measurement, the SN65LVCP1414 DC_GAIN and AC_GAIN are set through the RX_GAIN pin and there are only three possible RX_GAIN levels -> High, Low, and Hi-Z.
Table 8-2 lists the DC_GAIN and AC_GAIN associated with each level of RX_GAIN as shown below. I mapped the DC_GAIN and AC_GAIN setting with the actual value as shown below.
The only one I see missing is the last one on the list, but that is just changing the linearity range between 600mV (VOD = 0) and 1200mV (VOD =1)
So they can use the VOD = 0 s4p for their simulation and make sure the input signal amplitude stays within the 600mV linearity range to simulate the SN65LVCP1414 RX response.
Thanks
David
