ADDITIONAL TRANSCEIVERS
WITH THE SP504
Serial ports usually can have two data signals
(SD, RD), three clock signals (TT, ST, RT), and
at least eight control signals (CS, RS, etc.). EIA-
RS-449 contains twenty six signal types for a
DB-37 connector. A DB-37 serial port design
may require thirteen drivers and fourteen re-
ceivers
1
. Although many applications do not
use all these signals, some applications may
need to support extra functions such as diagnos-
tics. The
SP504
supports enough transceivers
for the primary channels of data, clock and
control signals. Configuring LL, RL and TM
would require two additional drivers and one
receiver if designing for a DTE (one driver and
two receivers for a DCE).
A programmable transceiver such as the SP332
is a convenient solution in a design that requires
extra single ended or differential drivers/receiv-
ers. As shown in
Figure 28
, the SP332 can be
configured to four different variations.
The SP332 in
Figure 29
is configured for two
single-ended drivers and one diffferential re-
ceiver. For a DTE design, the two drivers are
used for LL and RL signals and the receiver is
used for the TM signal. This configuration was
selected because the two RS-232 drivers can be

used for RS-423 by connecting a zener clamp-
ing diode to ground on the two driver outputs.
The diodes will limit the voltage swing on the
outputs so that the V
=
±
4V to
±
6V adheres to
the RS-423 specification. The differential re-
ceiver can be easily configured to RS-423 by
grounding the non-inverting input. The receiver
will adhere to the RS-423 specifications.
