SP503 Application Note

1

Due to its flexibility and programmability,

the SP503 has been finding its way into

many new networking products. The SP503

offers an excellent replacement for discrete

solutions on X.25 implementations for frame

relay systems, multi-protocol routers and

other WAN products where many designs

run various modes such as RS-232,

RS-422, V.35 or V.36.

For RS-232, the older bipolar 1488 and

1489 parts, or even the newer MAX230 or

SP230 series have traditionally been used.

For RS-422 or RS-485, the

26LS31,

26LS32, 3488, and 3489 have been seen in

many designs. These parts have been also

used for V.35 but with external termination

resistors. For a typical design, four RS-232

chips would be used for a complete

RS-232 port, four RS-422 chips for an

RS-422 port and four chips for V.35 with an

external resistor network. Port programma-

bility would require relays or switches so

that software lines can control whether

RS-232 is active or RS-422 is active. The

relays increase board capacity as well as

cost to the design.

The SP503 solves board space and cost

problems by offering a single packaged part

that supports various protocols and also

offers software programmability to the port.
