Using ADSP-TS201S EZ-KIT Lite
Processor Link Ports
The link ports on the ADSP-TS201S processor uses Low Voltage Differ-
ential Signaling (LVDS) to communicate with each other. Each processor
has a
TX
(transmit) port and
RX
(receive) port for each of its link ports. The
RJ-45 connectors,
J4–5
, are the
TX
and
RX
ports for processor A. Similarly,
J6–7
are
TX
and
RX
for processor B. The
TX
and
RX
of one processor’s link
ports should be respectively connected to
RX
and
TX
of another processor’s
link ports. In this manner, the
TX
of one processor connects to the
RX
of
the other processor.
Connect the link ports with a standard CAT 5E networking cable. The
length of the cable may affect the maximum frequency at which the data
can be transferred. Refer to the ADSP-TS201S embedded processor data
sheet at
http://www.analog.com/Uploaded-
Files/Data_Sheets/ADSP_TS201S.pdf
for more information.
There are four link ports on each of the processors on the EZ-KIT Lite.
For each processor, the Link Port 0 transmit signals are connected to the
receive of the same Link Port 0 signals. Link ports 2 and 3 connect the
transmit of one processor to the receive of the other processor.
Example Programs
Example programs are provided with the ADSP-TS201S EZ-KIT Lite to
demonstrate various capabilities of the evaluation board. These programs
are installed with the EZ-KIT Lite software and can be found in the
…\TS\Examples\ADSP-TS201 EZ-KIT Lite
subdirectory of the Visu-
alDSP++ installation directory. Please refer to the readme file provided
with each example program for more information.

When running the examples, do not change the
BGEN
or
NMOD
(8 or 9) bits in the
SQCTL
register. The change can disable commu-
nications with the host.
