Cyclone III devices provide a multi-protocol interface that allows
communication between a variety of I/O standards, including LVDS,
RSDS, mini-LVDS, PPDS, LVPECL, differential HSTL, and differential
SSTL. This feature makes the Cyclone III device family ideal for
applications that require multiple I/O standards, such as protocol
translation.
You can use I/O pins and internal logic to implement a high-speed I/O
receiver and transmitter in Cyclone III devices. Cyclone III devices do not
contain dedicated serialization or deserialization circuitry. Therefore,
shift registers, internal phase-locked loops (PLLs), and I/O cells are used
to perform serial-to-parallel conversions on incoming data and parallel-
to-serial conversion on outgoing data.
Table 8–2
shows the numbers of Cyclone III device differential channels.
