The differential peak and differential peak to peak voltage is defined as follows:
• V_DIFFp = max (|V₊ - V_-|)
• V_DIFFp-p = (2* V_DIFFp)
In addition, the transmitter must meet the following eye diagram.

Receive
The receiver operates with less than 10^-12 Bit Error Rate (BER) when the received signal meets
valid voltage and timing specifications and is delivered from a balanced 100 Ω source.
