Channel Interface
Description
Transmit Signal Description (Based on HardCopy IV GX Supported
Core fabric-Transceiver Channel Interface Widths)
Two 8-bit Data (tx_datain)
tx_datainfull[7:0] - tx_datain (LSByte) and
tx_datainfull[29:22] - tx_datain (MSByte)
The following signals are used only in 8B/10B modes:
Two Control Bits (tx_ctrlenable)
tx_datainfull[8] - tx_ctrlenable (LSB) and
tx_datainfull[30] - tx_ctrlenable (MSB)
16-bit Core
fabric-Transceiver Channel
Interface with PCS-PMA set
to 8/10 bits
Force Disparity Enable
For non-PIPE:
tx_datainfull[9] - tx_forcedisp (LSB) and
tx_datainfull[31] - tx_forcedisp (MSB)
For PIPE:
tx_datainfull[9] - tx_forcedispcompliance (LSB)
and tx_datainfull[31] - tx_forcedispcompliance
(MSB)
Force Disparity Value
tx_datainfull[10] - tx_dispval (LSB) and
tx_datainfull[32] - tx_dispval (MSB)
20-bit Core
fabric-Transceiver Channel
Interface with PCS-PMA set
to 20 bits
Two 10-bit Data (tx_datain)
tx_datainfull[9:0] - tx_datain (LSByte) and
tx_datainfull[20:11] - tx_datain (MSByte)
20-bit Core
fabric-Transceiver Channel
Interface with PCS-PMA set
to 10 bits
Two 10-bit Data (tx_datain)
