1.15. Ping Pong PHY

Ping Pong PHY is an implementation of UniPHY that allows two memory interfaces to share address and command buses through time multiplexing. Compared to having two independent interfaces, Ping Pong PHY uses fewer pins and less logic, while maintaining equivalent throughput.

The Ping Pong PHY supports only quarter-rate configurations of the DDR3 protocol on Arria V GZ and Stratix V devices.
