10M (Serial Interface) Receive Data.
This pin’s description is the same as that given in
Receive Data 1–3.
For the 10M Serial Interface, these pins are a no connect. For
more information, see
10M (Serial Interface) Receive Data Valid.
The ICS1892 asserts 10RXDV to indicate to the MAC/repeater
that data is available on the MII Receive Bus (RXD[3:0]). The
ICS1892:
Receive Error.
For the 10M Serial Interface, this pin is a no connect. For more
information, see
Receive (Interface), Tri-State.
The input on this pin is from a MAC. When the signal on this pin
is logic:
Transmit Error.
For the 10M Serial Interface, this pin is a no connect. For more
information, see
10M (Serial Interface) Transmit Clock.
In 10M Serial TXCLK is 10 MHz.
10M (Serial Interface) Transmit Data.
This pin’s description is the same as that given in

For the 10M Serial Interface, these pins are a no connect. For
more information, see
10M (Serial Interface) Transmit Enable.
This pin’s description is the same as that given in
Transmit Error.
For the 10M Serial Interface, these pins are a no connect. For

Asserts 10RXDV after it detects and recovers the
Start-of-Stream delimiter, /J/K/. (For the timing reference,
see
Synchronous Receive
De-asserts 10RXDV after it detects either the End-of-Stream
delimiter (/T/R/) or a signal error.
Low, the MAC indicates that it is not in a tri-state condition.
High, the MAC indicates that it is in a tri-state condition. In
this case, the ICS1892 acts to ensure that only one PHY is
active at a time.
