AN1057 discusses about the system parallel interface built with the CY7C9689A that are directly compatible with the legacy systems made using AMD TAXI™.
Introduction
The Cypress CY7C9689A TAXI-compatible HOTLink® Transceiver facilitates point-to-point data communication over high-speed serial links. Systems built with the CY7C9689A are directly compatible with legacy systems made using AMD TAXI chip devices. The CY7C9689A HOTLink Transceiver is functionally equivalent to an AMD AM7968 TAXI transmitter and AM7969 receiver pair, with numerous technology enhancements and extensions.
