MAX3172CAI+

The MAX3172CAI+ is a +3.3V multiprotocol software-selectable cable terminator and transceiver in 28 pin SSOP package. It contains five software-selectable multiprotocol cable termination networks. Each network is capable of terminating V.11 (RS422, RS530, RS530A, RS449, V.36 and X.21) with a 100 ohm differential load, V.35 with a T-network load or V.28 (RS232) and V.10 (RS423) with an open circuit load for use with transceivers having on-chip termination. The device replaces discrete resistor termination networks and expensive relays required for multiprotocol termination. The MAX3172 along with the MAX3170 and MAX3171 form a complete +3.3V software-selectable DTE or DCE interface port supporting V.11/RS422, RS530, RS530A, V.36/RS449, V.35, V.28/RS232, V.10/RS423 and X.21 serial interfaces. In addition to the five multiprotocol cable termination networks, the MAX3172 contain a 1Tx/1Rx multiprotocol transceiver designed to use V+ and V generated by the MAX3171/MAX3173 charge pump.
