Description

tx_parallel_data[43:0]

Input

PCS TX parallel data representing 4, 11-

bit words. Used when you enable the

Standard datapath. Refer to

Table

13-20

for bit definitions. Refer to

Table

13-21

various parameterizations.

rx_parallel_data[63:0]

Output

PCS RX parallel data, representing 4, 16-

bit words. Used when you enable the

Standard datapath. Refer to

Table 13-22

for bit definitions. Refer to

for various parameterizations.

TX and RX serial ports

tx_serial_data[-1:0]

Output

TX differential serial output data.

rx_serial_data[-1:0]

Input

RX differential serial output data.

Control and Status ports

rx_seriallpbken[-1:0]

Input

When asserted, the transceiver enters

serial loopback mode. Loopback drives

serial TX data to the RX interface.

rx_set_locktodata[-1:0]

Input

When asserted, programs the RX CDR to

manual lock to data mode in which you

control the reset sequence using the

rx_

set_locktoref

and

rx_set_

locktodata

. Refer to “Transceiver Reset

Sequence” in Transceiver Reset Control

in Arria V Devices for more information

about manual control of the reset

sequence.

rx_set_locktoref[-1:0]

Input

When asserted, programs the RX CDR to

manual lock to reference mode in which

you control the reset sequence using the

rx_set_locktoref

and

rx_set_

locktodata

. Refer to Refer to

“Transceiver Reset Sequence” in

Transceiver Reset Control in Arria V

Devices for more information about

manual control of the reset sequence.

pll_locked[

-1:0]

Output

When asserted, indicates that the PLL is

locked to the input reference clock.

rx_is_lockedtodata[-1:0]

Output

When asserted, the CDR is locked to the

incoming data.
