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 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
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.
