Receiver Input Buffer
Cyclone IV Device Handbook, Volume 2
The following sections describe the Cyclone IV GX receiver channel datapath
architecture as shown in
Table 1–2
buffer.
Table 1–2. Electrical Features Supported by the Receiver Input Buffer
The high-speed serial link can be AC- or DC-coupled, depending on the serial
protocol implementation. In an AC-coupled link, the AC-coupling capacitor blocks
the transmitter DC common mode voltage as shown in
and on-chip biasing circuitry automatically restores the common mode voltage. The
biasing circuitry is also enabled by enabling OCT. If you disable the OCT, then you
must externally terminate and bias the receiver. AC-coupled links are required for
PCIe, GbE, Serial RapidIO, SDI, XAUI, SATA, V-by-One and Display Port protocols.

Note to
(1) DC coupling is supported for LVDS with lower on-chip common mode voltage of 0.82 V.
