Pin Function
3.3V analog VDD
Media Dependent Interface[0], positive signal of differential pair
1000Base-T Mode:
TXRXP_A corresponds to BI_DA+ for MDI configuration and BI_DB+ for
MDI-X configuration, respectively.
10Base-T / 100Base-TX Mode:
TXRXP_A is the positive transmit signal (TX+) for MDI configuration and
the positive receive signal (RX+) for MDI-X configuration, respectively.
Media Dependent Interface[0], negative signal of differential pair
1000Base-T Mode:
TXRXM_A corresponds to BI_DA- for MDI configuration and BI_DB- for
MDI-X configuration, respectively.
10Base-T / 100Base-TX Mode:
TXRXM_A is the negative transmit signal (TX-) for MDI configuration and
the negative receive signal (RX-) for MDI-X configuration, respectively.
