DESCRIPTION

The SP506 is a monolithic IC that supports eight (8) popular serial interface standards for DTE

to DCE connectivity. The SP506 is pin-to-pin compatible to our SP505 multi-protocol transceiver

butwithfasterthroughput.Theseven(7)driversandseven(7)receiverscantransmitandreceive

signals at 20Mbps. As with the SP505, the SP506 requires no additional external components

for compliant operation for all of the eight (8) modes of operation. All necessary termination is

integrated within the SP506 and is switchable when V.35 drivers, V.35 receivers, and V.11

receivers are used. The SP506 can operate as either a DTE or DCE.

Additional features with the SP506 include internal loopback that can be initiated in either single-

ended or differential modes. While in loopback mode, driver outputs are internally connected to

receiver inputs creating an internal signal path convenient for diagnostic testing. This eliminates

theneedforanexternalloopbackplug. TheSP506alsoincludesalatchenablepinwiththedriver

and receiver address decoder. Tri-state ability for the driver and receiver outputs is controlled by

supplying a 4-bit word into the address decoder. Seven (7) drivers and one (1) receiver in the

SP506 include separate enable pins for added convenience.
