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.
