The CY7C9689A HOTLink Transceiver is a point-to-point communications building block allowing the transfer of data over high-speed serial links (optical fiber, balanced, and unbalanced copper transmission lines) at speeds ranging between 50 and 200 MBaud. The transmit section accepts parallel data of selectable widths and converts it to serial data, while the receiver section accepts serial data and converts it to parallel data of selectable widths. Figure 1 illustrates typical connections between two independent host systems and corresponding CY7C9689A parts. The CY7C9689A provides enhanced technology, increased functionality, a higher level of integration, higher data rates, and lower power dissipation over the AMD AM7968/7969 TAXIchip products. The transmit section of the CY7C9689A HOTLink can be configured to accept either 8- or 10-bit data characters on each clock cycle, and stores the parallel data into an internal synchronous Transmit FIFO.
