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 but with faster
throughput. The seven (7) drivers and seven (7) receivers can transmit and receive signals at 20Mbps.
As with 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 the need for
an external loopback plug. The SP506 also includes a latch enable pin with the driver 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.
