Parameter Value Description
Transceiver
mode
TX/RX Duplex
TX Simplex
RX Simplex
Specifies the operational mode of the transceiver.
• TX/RX Duplex : Specifies a single channel that supports
both transmit and receive capabilities.
• TX Simplex : Specifies a single channel that supports only
transmission.
• RX Simplex : Specifies a single channel that supports only
reception.
The default is TX/RX Duplex.
Number of data
channels
1 – <n>
Specifies the number of transceiver channels to be
implemented. The maximum number of channels available,
( <n> ), depends on the package you select.
The default value is 1.
Data rate < valid Transceiver
data rate >
Specifies the data rate in megabits per second (Mbps).
Enable datapath
and interface
reconfiguration
On/Off
When you turn this option on, you can preconfigure and
dynamically switch between the Standard PCS, Enhanced PCS,
and PCS direct datapaths.
The default value is Off.
Enable
simplified data
interface
On/Off
By default, all 128-bits are ports for the tx_parallel_data and
rx_parallel_data buses are exposed. You must understand
the mapping of data and control signals within the interface.
Refer to the Enhanced PCS TX and RX Control Ports section for
details about mapping of data and control signals.
When you turn on this option, the Transceiver Native PHY IP
presents a simplified data and control interface between the
FPGA fabric and transceiver. Only the sub-set of the 128-bits
that are active for a particular FPGA fabric width are ports.
The default value is Off.

Transceiver Configuration
Setting
Description
Basic/Custom (Standard
PCS)
Enforces a standard set of rules within the Standard PCS. Select these rules
to implement custom protocols requiring blocks within the Standard PCS
or protocols not covered by the other configuration rules.
(26)
This option cannot be used, if you intend to dynamically reconfigure between PCS datapaths, or
reconfigure the interface of the transceiver.
