The SP50x family of multi-protocol transceivers are
designed for applications using serial ports in
networking equipment such as routers, DSU/CSUs,
multiplexors, access devices, and other networking
equipment. This application note discusses and
helpful hints about designing with the SP505 and the
newer SP506 and SP507 products.
These one-chip serial port transceiver products
supports seven popular serial interface standards for
Wide Area Network (WAN) connectivity. With a
built-in DC-DC charge pump converter, the SP505,
SP506 and SP507 operate on +5V only. The seven
drivers and seven receivers can be configured via
software for RS-232, X.21, EIA-530, EIA-530A,
RS-449, V.35, and V.36 interface modes at any time.

Unlike other discrete solutions or other multi-chip
transceivers, the SP505, SP506 and SP507 require
no additional external circuitry for compliant
operation other than the charge pump capacitors.
All necessary resistor termination networks are
integrated within the SP505, SP506 and SP507, and
are switchable when in EIA-530, EIA-530A, RS-449,
V.35, V.36, and X.21 modes.
The SP505, SP506 and SP507 provide individual
driver disable for easy DTE/DCE configurations.
The SP507 offers four receiver enable lines for even
easier DTE/DCE programmability. The newer SP506
is pin compatible with the SP505 except with
improved AC performance. Refer to the SP505, SP506
and SP507 datasheets for electrical parameter and
configuration details.
