Output 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:
• Asserts 10RXDV after it detects and recovers the
Start-of-Stream delimiter, /J/K/. (For the timing reference,
see Chapter 10.5.6, “MII / 100M Stream Interface:
Synchronous Receive Timing”.)
• De-asserts 10RXDV after it detects either the End-of-Stream
delimiter (/T/R/) or a signal error.
Note: 10RXDV is synchronous with the Receive Data Clock,
10RCLK.

Input
Receive (Interface), Tri-State.
The input on this pin is from a MAC. When the signal on this pin
is logic:
• 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.
