Functional Description
The CY7B923 HOTLink Transmitter and CY7B933 HOTLink
Receiver are point-to-point communications building blocks
that transfer data over high-speed serial links (fiber, coax, and
twisted pair). Standard HOTLink data rates range from
160-330 Mbits/second. Higher speed HOTLink is also avail-
able for high speed applications (160-400 Mbits/second), as
well as for those Low Cost applications HOTLink-155 (150-160
Mbits/second operations). Figure 1 illustrates typical connec-
tions to host systems or controllers.
Eight bits of user data or protocol information are loaded into
the HOTLink transmitter and are encoded. Serial data is shift-
ed out of the three differential positive ECL (PECL) serial ports
at the bit rate (which is 10 times the byte rate).
The HOTLink receiver accepts the serial bit stream at its dif-
ferential line receiver inputs and, using a completely integrated
PLL Clock Synchronizer, recovers the timing information nec-
essary for data reconstruction. The bit stream is deserialized,
decoded, and checked for transmission errors. Recovered
bytes are presented in parallel to the receiving host along with
a byte-rate clock.
The 8B/10B encoder/decoder can be disabled in systems that
already encode or scramble the transmitted data. I/O signals
are available to create a seamless interface with both asyn-
chronous FIFOs (i.e., CY7C42X) and clocked FIFOs (i.e.,
CY7C44X). A Built-In Self-Test pattern generator and checker
allows testing of the transmitter, receiver, and the connecting
link as a part of a system diagnostic check.
HOTLink devices are ideal for a variety of applications where
a parallel interface can be replaced with a high-speed
point-to-point serial link. Applications include interconnecting
workstations, servers, mass storage, and video transmission
equipment.
