All Supported Functional Modes Except the PCIe Functional Mode
This section describes reset sequences for transceiver channels in bonded and
non-bonded configurations. Timing diagrams of some typical configurations are
shown to facilitate proper reset sequence implementation. In these functional modes,
you can set the receiver CDR either in automatic lock or manual lock mode.
1
In manual lock mode, the receiver CDR locks to the reference clock (lock-to-reference)
or the incoming serial data (lock-to-data), depending on the logic levels on the
rx_locktorefclk and rx_locktodata signals. With the receiver CDR in manual
lock mode, you can either configure the transceiver channels in the Cyclone IV GX
device in a non-bonded configuration or a bonded configuration. In a bonded
configuration, for example in XAUI mode, four channels are bonded together.
