The SP3508 is fabricated using a low power BiCMOS process technology, and incorporates a Sipex regulated charge pump allowing +3.
3V only operation.
Sipex's patented charge pump provides a regulated output of +5.
5V, which will provide 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 the eight (8) modes of operation other than six capacitors used for the internal charge pump.
All necessary termination is integrated within the SP3508 and is switchable when V.
35 drivers and V.
35 receivers, or when V.
11 receivers are used.
The SP3508 provides the controls and transceiver availability for operating as either a DTE or DCE.
Additional features with the SP3508 include internal loopback that ca...
