Description

RX Channel

Enable RX channel reset control

On /Off

When On, the Transceiver PHY Reset

Controller enables the control logic and

associated status signals for RX reset. When Off,

disables RX reset control and status signals.

Use separate RX reset per channel On /Off

When On, each RX channel has a separate reset

input. When Off, uses a shared RX reset

controller for all channels.

RX digital reset mode

Auto, Manual,

Expose Port

Specifies the Transceiver PHY Reset Controller

behavior when the PLL lock signal is deasserted.

The following modes are available:
Auto—The associated

rx_digital_reset

controller automatically resets whenever the

rx_is_lockedtodata

signal is deasserted.

Manual—The associated

rx_digital_reset

controller is not reset when the

rx_is_

lockedtodata

signal is deasserted, allowing

you to choose corrective action.

Expose Port—The

rx_manual

signal is a

top-level signal of the IP core. If the core

includes separate reset control for each RX

channel, each RX channel uses its respective

rx_is_lockedtodata

signal for automatic

reset control; otherwise, the inputs are

ANDed to provide internal status for the

shared reset controller.

rx_analogreset duration

1-999999999

Specifies the time in ns to continue to assert the

rx_analogreset

after the reset input and all

other gating conditions are removed. The value

is rounded up to the nearest clock cycle. The

default value is 40 ns.

rx_digitalreset duration

1-999999999

Specifies the time in ns to continue to assert the

rx_digitalreset

after the reset input and all

other gating conditions are removed. The value

is rounded up to the nearest clock cycle. The

default value is 4000 ns.

Transceiver PHY Reset Controller Interfaces

This section describes the top-level signals for the Transceiver PHY Reset Controller IP core.
The following figure illustrates the top-level signals of the Transceiver PHY Reset Controller IP core.

Many of the signals in the figure become buses if you choose separate reset controls. The variables in the

figure represent the following parameters:
—The number of lanes

—The number of PLLs
