Collision (Detect).
For the Link Pulse Interface, this pin is a no connect. For more
information, see
Carrier Sense.
For the Link Pulse Interface, this pin is a no connect. For more
information, see
Link Pulse (Interface) Receive Error.
This pin’s description is the same as that given in
Link (Pulse Interface) Receive Clock.
The ICS1892 sources the LRCLK to the MAC/repeater. The
ICS1892 uses LRCLK to synchronize the signals on the LPRX
pin. The signal on the LRCLK pin is conditioned by RXTRI.
Management Data Clock.
This pin’s description is the same as that given in
Management Data Input/Output.
This pin’s description is the same as that given in
Receive Data 0–3.
For the Link Pulse Interface, these pins are a no connect. For
more information, see
Receive Data Valid.
For the Link Pulse Interface, this pin is a no connect. For more
information, see
Link Pulse (Interface) Receive Error.
This pin’s description is the same as that given in
Receive (Interface), Tri-State.
The input on this pin is from a MAC. When the signal on this pin is
logic:
Link (Pulse Interface) Transmit Clock.
This pin’s description is the same as that given in
Transmit Data 0–3.
For the Link Pulse Interface, these pins are a no connect. For
more information, see

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.
