Receive Error.
When the MAC/Repeater Interface is in:
Receive (Interface), Tri-State.
The input on this pin is from a MAC. When the signal on this pin is logic:
Transmit Clock.
The ICS1893CY-10 generates this clock signal to synchronize the transfer
of data from the MAC/Repeater Interface to the ICS1893CY-10. When the
mode is:
Transmit Data 0–3.
1. An ICS1893CY-10 asserts a signal on the RXER pin upon detection of
2. The RXER signal always transitions synchronously with RXCLK.
3. The signal on RXER pin is conditioned by the RXTRI pin.

10M MII mode, RXER is not used.
100M MII mode, the ICS1893CY-10 asserts a signal on the RXER pin
when either of the following two conditions are true:
– Errors are detected during the reception of valid frames
– A False Carrier is detected
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.
10Base-T, the TXCLK frequency is 2.5 MHz.
100Base-TX, the TXCLK frequency is 25 MHz.
TXD0 is the least-significant bit and TXD3 is the most-significant bit of
the MII transmit data nibble received from the MAC/repeater.
The ICS1893CY-10 samples its TXEN signal to determine when data
is available for transmission. When TXEN is asserted, the signals on a
the TXD[3:0] pins are sampled synchronously on the rising edges of
the TXCLK signal.
a False Carrier so that repeater applications can prevent the
propagation of a False Carrier.
