+5V Multiprotocol, Software-Selectable Cable Terminator
General Description
The MXL1344A contains six software-selectable, multiprotocol cable termination networks. Each network is capable of terminating V.11 (RS-422, RS-530, RS-530A, RS-449, V.36 and X.21) with a 100Ω differential load, V.35 with a T-network load, or V.28 (RS-232) and V.10 (RS-423) with an open-circuit load for use with transceivers having on-chip termination. The termination protocol can be selected by the serial interface cable wiring or by software control. The MXL1344A replaces discrete resistor termination networks and expensive relays required for multiprotocol termination, saving space and cost.
