All rights reserved.
The ICS1893Y-10’s SRD0 pin transmits the least-significant
bit and the SRD4 pin transmits the most-significant bit of the
symbol received from its MAC/Repeater interface.
The ICS1893Y-10 continually transfers the data it receives
from its MDI to its SRD[4:0] pins (that is, to its MAC/Repeater
Interface). In the 100M Symbol mode, data is not framed.
Therefore, the ICS1893Y-10 does not assert its RXDV
signal.
The ICS1893Y-10 transfers its receive data to the SRD[4:0]
pins synchronously on the rising edges of its SRCLK signal.
Low, the MAC indicates it is not in a tri-state condition.
High, the MAC indicates it is in a tri-state condition. In this
case, the ICS1893Y-10 acts to ensure that only one PHY is
active at a time. (A PHY address of 00 also tri-states the MII
interface.)
The ICS1893Y-10 STD0 pin receives the least-significant bit
and the STD4 pin receives the most-significant bit of the
symbol received from the MAC/Repeater interface.
The signals on the ICS1893Y-10 STD[4:0] pins are
continually and synchronously sampled on the rising edges
of its STCLK. These signals are independent of the TXEN
signal.

MAC/Repeater is responsible for sending both IDLE
symbols and data.
