Functional Description The CY7B923 HOTLink‚ Transmitter and CY7B933 HOTLink Receiver are point-to-point communications building blocks that transfer data over high-speed serial links (fiber, coax, and twisted pair). Standard HOTLink data rates range from 160 to 330 Mbits/second. Higher speed HOTLink is also available for high-speed applications (160–400 Mbits/second), as well as, for low-cost applications, HOTLink-155 (150–160 Mbits/second operations). Figure 1 illustrates typical connections to host systems or controllers.
