Description

3.3V/2.5V (commercial temperature only) 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.

1.2V analog VDD

1.2V analog VDD

No connect
