Functional Description

The CYP15G0401RB Quad HOTLink II? Receiver is a point-to-point or point-to-multipoint communications building block allowing the transfer of data over high-speed serial links (optical fiber, balanced, and unbalanced copper transmission lines) at signaling speeds ranging from 195-to-1500 MBaud per serial link.

Each receive channel accepts serial data and converts it to parallel data, decodes the data into characters, and presents these characters to an Output Register. Figure 1 illustrates typical connections between independent host systems and corresponding CYP15G0401TB and CYP15G0401RB parts.
