Each transceiver block has the following components:
1. Four full-duplex (transmitter and receiver) transceiver channels that support serial
2. Two CMU channels—CMU0 and CMU1 channels—that provide the high-speed serial
3. Central control unit (CCU) that implements the XAUI state machine for
data rates from 600 Mbps to 8.5 Gbps in Stratix IV GX devices and 600 Mbps to
11.3 Gbps in Stratix IV GT devices. For more information, refer to
Channel Architecture” on page
and low-speed parallel clock to the transceiver channels. For more information,
refer to
XGMII-to-PCS code group conversion, XAUI deskew state machine, shared
control signal generation block, PCIe rateswitch controller block, and reset control
logic
■
■
The shared control signal generation block provides control signals to the
transceiver channels in bonded functional modes, such as XAUI, PCIe, and
Basic ×4.
The PCIe rateswitch controller block controls the rateswitch circuit in the CMU0
channel in ×4 configurations. In PCIe ×8 configuration, the PCIe rateswitch
controller block of the CCU in the master transceiver block is active. For more
information, refer to
“CMU Channel Architecture” on page
