Receiver Input Buffer
The receiver input buffer receives serial data from the rx_datain port and feeds it to
the CDR unit.

Table 1–6
Table 1–6. Electrical Features Supported by the Receiver Input Buffer for Arria II
Devices
The following sections describe the features supported in the Arria II GX and GZ
receiver input buffers.
Programmable Differential OCT
The Arria II GX and GZ receiver input buffers support optional differential OCT of
85  (Arria II GZ only) or 100 
compensate for temperature, voltage, and process changes (for more information,
refer to
Assignment Editor by setting the assignment input termination to OCT 100  on the
receiver input buffer.
From Serial Data
Note to
(1) The differential OCT setting for Arria II GX and GZ transmitters and receivers is 85 (Arria II GZ only) or 100  .
