Stratix IV GX Devices
Stratix IV GX devices provide up to 48 full-duplex CDR-based transceiver channels
per device:
■
Thirty-two out of the 48 transceiver channels have dedicated physical coding
sublayer (PCS) and physical medium attachment (PMA) circuitry and support
data rates between 600 Mbps and 8.5 Gbps
The remaining 16 transceiver channels have dedicated PMA-only circuitry and
support data rates between 600 Mbps and 6.5 Gbps
■
