Functional Description
The CYP15G0402DX Quad HOTLinkII
SERDES is a
point-to-point communications building block allowing the
transfer of pre-encoded data over high-speed serial links
(optical fiber, balanced, and unbalanced copper transmission
lines) at speeds ranging from 200 to 1500 MBaud per serial
link.
Each transmit channel accepts pre-encoded 10-bit trans-
mission characters in an input register, serializes each
character, and drives it out a PECL-compatible differential line
driver. Each receive channel accepts a serial data stream at a
differential line receiver, deserializes the stream into 10-bit
characters, frames these characters to the proper 10-bit
character boundaries, and this data becomes register outputs
with a recovered character clock.
