You can use I/O pins and internal logic to implement a high-speed differential
interface in Cyclone IV devices. Cyclone IV 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. The
differential interface data serializers and deserializers (SERDES) are automatically
constructed in the core logic elements (LEs) with the Quartus II software ALTLVDS
megafunction.
