Detailed Description
The MXL1543 is a three-driver/three-receiver, multipro-
tocol transceiver that operates from a single +5V sup-
ply. The MXL1543, along with the MXL1544/MAX3175
and MXL1344A, form a complete software-selectable
DTE or DCE interface port that supports the V.28 (RS-
232), V.10/V.11 (RS-449/V.36, EIA-530, EIA-530A,
X.21), and V.35 protocols. The MXL1543 transceivers
carry the high-speed clock and data signals, while the
MXL1544/MAX3175 transceivers carry serial interface
control signaling. The MXL1543 can be terminated by
the MXL1344A software-selectable resistor termination
network or by a discrete termination network. The
MXL1543 features a 0.5A no-cable mode, true fail-
safe operation, and thermal shutdown circuitry. Thermal
shutdown protects the drivers against excessive power
dissipation. When activated, the thermal shutdown cir-
cuitry places the driver outputs into a high-impedance
state.
Mode Selection
The state of the mode-select pins M0, M1, and M2
determines which serial interface protocol is selected
(Table 1). The state of the DCE/DTE input determines
whether the transceiver will be configured as a DTE or
DCE serial port. When the DCE/DTE input is logic
HIGH, driver T3 is activated and receiver R1 is dis-
abled. When the DCE/DTE input is logic LOW, driver T3
