HIV51008-2.2 8. High-Speed Differential I/O Interfaces and DPA in HardCopy IV Devices HIV51008-2.2

By 

Abstract

The HardCopy ® IV device family offers up to 1.25-Gbps differential I/O capabilities to support source-synchronous communication protocols such as Utopia, RapidIO ®, XSBI, SGMII, SFI, and SPI. HardCopy IV and Stratix ® IV devices have identical circuitry for high-speed differential I/O interfaces and dynamic phase alignment (DPA). HardCopy IV high-speed I/Os support the same I/O standards and implementation guidelines as Stratix IV devices. You can prototype high-speed interfaces with Stratix IV devices and map the design to HardCopy IV devices. 1 Because of differences in resource availability, you must set the HardCopy IV companion device option in the Quartus ® II software to map your Stratix IV project to a HardCopy IV device. HardCopy IV devices have the same dedicated circuitry as Stratix IV devices for high-speed differential I/O support
