SP504
Application Note
The introduction of our SP502 transceiver paved
the way for a new generation of multi-mode
transceivers that are being designed into next
generation networking products. The SP504
multi-mode transceiver is the latest member of
the family and offers: reduced external V.35
termination; V.36 & EIA-530A modes; and
receiver tri-state and fail-safe ability.
As with the SP502 and SP503, the SP504 can be
programmed via software to the different avail-
able physical protocols and is also drop-in com-
patible with its predecessors.
The versatility of the SP504 is ideal for multi-
protocol applications such as Frame Relay sys-
tems, X.25 routers/switches and multi-protocol
routers. These multi-protocol systems will usu-
ally contain multiple ports to accommodate the
different interfaces. The SP504 can support all
the ports through software and provide conve-
nient DTE or DCE functionality to the port. DTE
and DCE configuration is provided on the next
page and also in the SP504 data sheet.
The designer can evaluate the SP504 with
our SP504 Evaluation Board. This evaluation
board basically allows the user to access the
pins directly through probe points on the board.
The designer can also access the device by
software through the three serial port connec-
tors on the board. Details on the evaluation
board can be found in the SP504 data sheet.
