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
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 1–11 For more information about transceiver architecture, refer to the Transceiver Figure 1–1 shows a high-level Stratix IV GX chip view.
(1) Resource counts vary with device selection, package selection, or both.
