Functional Description
The CYP(V)15G0403DXB[1] Independent Clock Quad HOTLink II™ Transceiver is a point-to-point or point-to-multipoint communications building block enabling transfer of data over a variety of high-speed serial links like optical fiber, balanced, and unbalanced copper transmission lines. The signaling rate can be anywhere in the range of 195 to 1500 MBaud per serial link.
