The ICS1893CY-10 samples its TXEN signal to determine when data
is available for transmission. When TXEN is asserted, the
ICS1893CY-10 begins sampling the data nibbles on the transmit data
lines TXD[3:0] synchronously with TXCLK. The ICS1893CY-10 then
transmits this data over the media.
Following the de-assertion of TXEN, the ICS1893CY-10 terminates
transmission of nibbles over the media.

In Symbol Mode, the ICS1893CY-10 sources an SRCLK to a
MAC/repeater. The SRCLK synchronizes the signals on the
SRD[4:0] pins between the ICS1893CY-10 and the
MAC/repeater. The SRCLK frequency is 25MHz.
