RXDV
36
Output
Receive Data Valid.
The ICS1892 asserts RXDV to indicate to the MAC/repeater that data is
available on the MII Receive Bus (RXD[3:0]). The ICS1892:
Asserts RXDV 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 RXDV after it detects either the End-of-Stream delimiter
(/T/R/) or a signal error.
Note:
RXDV is synchronous with the Receive Data Clock, RXCLK.
RXER
38
Output
Receive Error.
In 100Base-TX mode, the ICS1892 asserts a signal on the RXER pin
under two conditions:
When errors are detected during the reception of valid frames.
When a False Carrier is detected.
Note:
1. The ICS1892 asserts a signal on RXER upon detection of a False
Carrier so that repeater applications can prevent the propagation of a
False Carrier.
2. RXER always transitions synchronously with RXCLK.
RXTRI
39
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.
PHY address 00 will also act as RXTRI.
Transmit Clock.
The ICS1892 generates this clock signal to synchronize the transfer of
data from the MAC/Repeater Interface to the ICS1892. When the mode is:
10Base-T, the TXCLK frequency is 2.5 MHz.
100Base-TX, the TXCLK frequency is 25 MHz.
Transmit Data 0–3.
TXD0 is the least-significant bit and TXD3 is the most-significant bit of
the MII transmit data nibble received from the MAC/repeater.
While the ICS1892 asserts TXEN, the signals on the TXD0–TXD3 pins
are sampled by the ICS1892 synchronously on the rising edges of
TXCLK.
