General Description
The MXL1344A contains six software-selectable, multi-
protocol 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 100
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 trans-
ceivers having on-chip termination. The termination pro-
tocol 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.
The MXL1344A terminator is designed to form a com-
plete +5V cable- or software-selectable multiprotocol
DCE/DTE interface port when used with the MXL1543
and MXL1544/MAX3175 transceiver ICs. The MXL1344A
terminator can use the VEE power generated by the
MXL1543 charge pump, simplifying system design. The
MXL1344A, MXL1543, and MXL1544/MAX3175 are pin-
for-pin compatible with the LTC1344A, LTC1543, and
LTC1544, but for proper operation the entire Maxim
chipset must be used without substituting other manu-
facturer's parts on a chip-by-chip basis.
The MXL1344A is available in a 24-pin SSOP package
and is specified for the 0°C to +70°C commercial tem-
perature range.
