This application note discusses how to migrate from HOTLink-based designs to HOTLink II-based designs. While most designs can be converted from HOTLink to HOTLink II, applications that use the device at signaling rates of less than 200 Mbaud cannot be migrated. The scope of this application note is limited to device configuration, although some information on device operation is covered as necessary. The Quad HOTLink II Transceiver (CYP15G0401DXB) is used to illustrate how to migrate your design and one of the channels is used to show how to interface the HOTLink device to the HOTLink II devices.
