Designing with the

SP505, SP506, & SP507

Multi-Protocol

Serial Transceivers

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

illustrates various configuration options, and other

helpful hints about designing with the SP505 and the

newer SP506 and SP507 products.

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.

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.

The SP505, SP506 and SP507 provide individual

driver disable for easy DTE/DCE configurations.

The SP507 offers four receiver enable lines for even

easierDTE/DCEprogrammability. ThenewerSP506

is pin compatible with the SP505 except with

improvedACperformance.RefertotheSP505,SP506

and SP507 datasheets for electrical parameter and

configuration details.
