17. Transceiver Reconfiguration Controller IP Core Overview

The Altera Transceiver Reconfiguration Controller dynamically reconfigures analog settings in Arria V, Arria V GZ, Cyclone V, and Stratix V devices. Dynamic reconfiguration allows you to compensate for variations due to process, voltage, and temperature (PVT) in 28-nm devices.

Dynamic reconfiguration is required for Arria V, Arria V GZ, Cyclone V, and Stratix V devices that include transceivers. The reconfiguration functionality available in Arria V and Cyclone V devices is a subset of the functionality available for Stratix V devices.

Note: Some of the reconfiguration features not available for Arria V and Cyclone V devices in the current release, may be available in subsequent releases. Arria V and Cyclone V devices do not include ATX PLLs. Stratix V and Arria V GZ devices include ATX PLLs.
