ICS1893CY-10 Data Sheet - Release
Default
lists the pin mappings for the ICS1893CY-10 100M Symbol Interface mode.
No connect. [Because the MAC/repeater sources both active and ‘idle’ data, a PHY
cannot distinguish between an active and idle transmission channel (that is, to a PHY
the transmit channel always appears active). Therefore, a PHY cannot accurately
detect a collision.]

No connect. (Data exchanged between the MAC/repeater and a PHY is not framed in
the 100M Symbol Interface mode. Therefore, RXDV has no meaning.)

No connect. (100Base-TX operations require continuous transmission of data.
Therefore, the MAC/repeater is responsible for sourcing IDLE symbols when it is not
transmitting data.)
