RXDV
10RXDV 36
Output
10M (Serial Interface) Receive Data Valid.
The ICS1893CY-10 asserts 10RXDV to indicate to the
MAC/repeater that data is available on the MII Receive Bus
(RXD[3:0]). The ICS1893CY-10:
• Asserts 10RXDV after it detects and recovers the
Start-of-Stream delimiter, /J/K/. (For the timing reference,
see Chapter 9.5.6, “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.
RXER –

No Receive Error.
connect For the 10M Serial Interface, this pin is a no connect. For more
information, see Table 5-2.
RXTRI
41 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 ICS1893CY-10 acts to ensure that only one
PHY is active at a time.
• If the PHY address is 00, the ICS1893CY-10 acts as if the
RX-TRI pin is held high.
