Functional Description

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.
