Industrial-grade 10/100 Mbps Fast Ethernet Physical Layer Single Chip Transceiver
Differential data is received from the media
Differential data is transmitted to the media in TP mode
LED Driver output 0
OP0: (power up reset latch input)
This pin is used to control the forced or advertised operating mode of the
DM9161BI according to the Table A. The value is latched into the
DM9161BI registers at power-up/reset
LED Driver output 1
OP1: (power up reset latch input)
This pin is used to control the forced or advertised operating mode of the
DM9161BI according to the Table A. The value is latched into the
DM9161BI registers at power-up/reset
LED Driver output 2
OP2: (power up reset latch input)
This pin is used to control the forced or advertised operating mode of the
DM9161BI according to the Table A. The value is latched into the
DM9161BI registers at power-up/reset
Power Down Control
Asserted high to force the DM9161BI into power down mode. When in
power down mode, most of the DM9161BI circuit block’s power is turned
off, only the MII management interface (MDC, MDIO) logic is available
(the PHY should respond to management transactions and should not
generate spurious signals on the MII)). To leave power down mode, the
DM9161BI needs the hardware or software reset with the PWRDWN pin
low
Cable Status or Link Status
This pin is used to indicate the status of the cable connection when
power up reset latch low (Default)
0 = Without cable connection
1 = With cable connection
This pin is used to indicate the status of the Link connection when power
up reset latch high
HP Auto-MDIX Control
1: Disable auto mode
0: Enable HP Auto-MDIX mode
1 = Without link
0 = With link
