Description
Transmit Signal Description (Based on HardCopy IV GX Supported
Core fabric-Transceiver Channel Interface Widths)
tx_datainfull[7:0]: 8-bit data (tx_datain)
8-bit Core
fabric-Transceiver Channel
Interface
10-bit Core
fabric-Transceiver Channel
Interface
The following signals are used only in 8B/10B modes:
tx_datainfull[8]: Control bit (tx_ctrlenable)
tx_datainfull[9]: Force disparity enable for
tx_datainfull[7:0] (non PIPE mode).
Transmitter force disparity Compliance (PIPE) (tx_forcedisp) in
all modes except PIPE.
For PIPE mode, (tx_forcedispcompliance) is used.
tx_datainfull[10]: Forced disparity value for
tx_datainfull[7:0] (tx_dispval)
tx_datainfull[9:0]: 10-bit data (tx_datain)
Two 8-bit Data (tx_datain)
tx_datainfull[7:0] - tx_datain (LSByte) and
tx_datainfull[18:11] - tx_datain (MSByte)
The following signals are used only in 8B/10B modes:
16-bit Core
fabric-Transceiver Channel
Interface with PCS-PMA set
to 16/20 bits
tx_datainfull[8] - tx_ctrlenable (LSB) and
tx_datainfull[19] - tx_ctrlenable (MSB)
Force Disparity Enable
tx_datainfull[9] - tx_forcedisp (LSB) and
tx_datainfull[20] - tx_forcedisp (MSB)
Force Disparity Value
tx_datainfull[10] - tx_dispval (LSB) and
tx_datainfull[21] - tx_dispval (MSB)
