Receive Path
Table 20 lists the receive path characteristics. All test inputs are driven through an AC coupling network
shown in Figure 29. The receive bit stream is measured at the DX pin. RXEN=1.

Note 1: RXG controls the amount of gain or attenuation of the receiver analog gain element as specified
in Table 20. The overall receiver channel gain has 6 dB of attenuation and the net effect of the
RXG bits on the receiver channel gain is defined in Table 36.
