Product Summary

The SP3508 is a monolithic device that supports eight (8) popular serial interface standardsfor Wide Area Network (WAN) connectivity. The SP3508 is fabricated using a low powerBiCMOS process technology, and incorporates a regulated charge pump allowing +3.3V onlyoperation. Exar's patented charge pump provides a regulated output of +5.5V, which willprovide enough voltage for compliant operation in all modes. Eight (8) drivers and eight (8)receivers can be configured via software for any of the above interface modes at any time.The SP3508 requires no additional external components for compliant operation for all of theeight (8) modes of operation other than six capacitors used for the internal charge pump. Allnecessary termination is integrated within the SP3508 and is switchable when V.35 driversand V.35 receivers, or when V. receivers are used. The SP3508 provides the controls andtransceiver availability for operating as either a DTE or DCE.
