SP516DS/02

SP516 20Mbps 7 Driver, 7 Reciver Multiprotocol Serial Transceiver

© Copyright 2000 Sipex Corporation

The SP516 is a monolithic device that supports eight (8) popular serial interface standards for

DTE to DCE connectivity. The seven (7) drivers and seven (7) receivers can transmit and receive

signals over 20Mbps. The SP516 requires no additional external components for compliant

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

within the SP516 and is switchable when V.35 drivers, V.35 receivers, and V.11 receivers

are used. The SP516 can operate as either a DTE or DCE.

Additional features with the SP516 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 SP516 includes a termination network

disable pin for the V.35 and V.11 receiver input termination circuitry. High-Z 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 SP516 include separate enable pins for added convenience.
