source-synchronous circuitry Definition

Dedicated circuitry for Stratix^® series devices for supporting differential I/O standards at speeds up 1600 Mbps. Stratix^® series devices support up to 12.5 Gbps when using dynamic phase alignment (DPA). Device source-synchronous circuitry supports the 3.3-VPCML, LVDS, LVPECL, and HyperTransport I/O standards. Differential I/O standard support varies depending on the device selected.
