Description

3.3V/2.5V (commercial temp 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

Media Dependent Interface[1], positive signal of differential pair

1000BASE-T mode:

TXRXP_B corresponds to BI_DB+ for MDI configuration and BI_DA+ for MDI-

X configuration, respectively.

10BASE-T/100BASE-TX mode:

TXRXP_B is the positive receive signal (RX+) for MDI configuration and the

positive transmit signal (TX+) for MDI-X configuration, respectively.

Media Dependent Interface[1], negative signal of differential pair

1000BASE-T mode:

TXRXM_B corresponds to BI_DB– for MDI configuration and BI_DA– for

MDI-X configuration, respectively.

10BASE-T/100BASE-TX mode:

TXRXM_B is the negative receive signal (RX–) for MDI configuration and the

negative transmit signal (TX–) for MDI-X configuration, respectively.

Media Dependent Interface[2], positive signal of differential pair

1000BASE-T mode:

TXRXP_C corresponds to BI_DC+ for MDI configuration and BI_DD+ for

MDI-X configuration, respectively.

10BASE-T/100BASE-TX mode:

TXRXP_C is not used.

Media Dependent Interface[2], negative signal of differential pair

1000BASE-T mode:
