Figure 1–12. AC-Coupled Link with OCT
In a DC-coupled link, the transmitter DC common mode voltage is seen unblocked at
the receiver input buffer as shown in
depends on the transmitter common mode voltage and the receiver common mode
voltage. When using the receiver OCT and on-chip biasing circuitry in a DC coupled
link, you must ensure the transmitter common mode voltage is compatible with the
receiver common mode requirements. If you disable the OCT, you must terminate and
bias the receiver externally and ensure compatibility between the transmitter and the
receiver common mode voltage.
