Stratix IV GT Devices
Stratix IV GT devices provide up to 48 CDR-based transceiver channels per device:
■
Thirty-two out of the 48 transceiver channels have dedicated PCS and PMA
circuitry and support data rates between 600 Mbps and 11.3 Gbps
■
The remaining 16 transceiver channels have dedicated PMA-only circuitry and
support data rates between 600 Mbps and 6.5 Gbps
1 The actual number of transceiver channels per device varies with device selection. For
more information about the exact transceiver count in each device, refer to
Table 1–71 For more information about Stratix IV GT devices and transceiver architecture, refer
Figure 1–3 shows a high-level Stratix IV GT chip view.
