Altera has two PHY offerings, ALTMEMPHY, for low-power applications, and
UniPHY, for high-performance applications where UniPHY provides half the latency
of ALTMEMPHY. Some new features have been added to UniPHY to support the
needs of high-performance applications, including PLL and DLL sharing, support for
QDR II/II+ and RLDRAM II, and a new smart-calibration algorithm. In addition to
the new features, UniPHY has been architected to reduce the latency through the
