This design generates two transceiver PHY reset controllers—one for TX and one for RX. These reset
controllers are connected to the transceiver to control the reset sequence. The PHY adapter controls the
rx_manual
and
rx_is_lockedtodata
input signals of the reset controller. If you want to bypass the PHY
adapter, you must copy the assignment of these input signals in the
sdi_ii_phy_adapter.v
file to your design.
The table below describes how you should connect the input signals.
Table 3-4: Connecting Input Signals
Input Signal
Connection
rx_manual
Connect this signal to the
rx_ready
port of the PHY reset controller to
avoid any disturbance from short interference after the receiver is
locked.
rx_is_lockedtodata
Connect this signal to an output from a multiplexer between
rx_is_
lockedtoref
and
rx_is_lockedtodata
ports from the transceiver,
with the
rx_set_locktoref
acting as the selector. The receiver operates
in
locktoref
mode when it receives SD video data.
rx_is_lockedto-
data
is not stable in this mode.
Note: The Transceiver Reconfiguration Controller that was used in the design examples for Arria V,
Cyclone V, and Stratix V devices are not applicable for Arria 10 devices. The reconfiguration
interface is now integrated into the transceiver. Each transceiver should pair with a reconfiguration
controller if it requires reconfiguration.
Design Examples for Arria V, Cyclone V, and Stratix V Devices
Figure below illustrates the generated design example entity and simulation testbench for Arria V,
Cyclone V, and Stratix V devices. This design example consists of a video pattern generator, transceiver
reconfiguration controller, reconfiguration management, loopback path, and various SDI blocks
occupying two transceiver channels.
