Signal Description
Transmit Data - Port 3.
Inputs containing 2-bit parallel di-bits to be transmitted
from port 3 are clocked in synchronously to REFCLK.
Transmit Data - Port 4.
Inputs containing 2-bit parallel di-bits to be transmitted
from port 4 are clocked in synchronously to REFCLK.
Transmit Data - Port 5.
Inputs containing 2-bit parallel di-bits to be transmitted
from port 5 are clocked in synchronously to REFCLK.
Transmit Data - Port 6.
Inputs containing 2-bit parallel di-bits to be transmitted
from port 6 are clocked in synchronously to REFCLK.
Transmit Data - Port 7.
Inputs containing 2-bit parallel di-bits to be transmitted
from port 7 are clocked in synchronously to REFCLK.
Transmit Enable - Ports 0-7.
Active High input enables respective port transmitter.
This signal must be synchronous to the REFCLK.
Receive Data - Port 0.
Receive data signals (2-bit parallel di-bits) are driven
synchronously to REFCLK.
Receive Data - Port 1.
Receive data signals (2-bit parallel di-bits) are driven
synchronously to REFCLK.
Receive Data - Port 2.
Receive data signals (2-bit parallel di-bits) are driven
synchronously to REFCLK.
Receive Data - Port 3.
Receive data signals (2-bit parallel di-bits) are driven
synchronously to REFCLK.
Receive Data - Port 4.
Receive data signals (2-bit parallel di-bits) are driven
synchronously to REFCLK.
Receive Data - Port 5.
Receive data signals (2-bit parallel di-bits) are driven
synchronously to REFCLK.
