configured for V.10 or V.28 operation as a driver or
receiver (Table 3). This mode-selection table is compati-
ble for use with the MAX3170 (clock/data transceiver)
and the MAX3171/MAX3173 (control transceiver). For
example, if X.21 mode is selected in DCE mode (M2 = 0,
M1 = 1, M0 = 1, and DCE/
DTE
= 1), the MAX3170,
MAX3171/MAX3173, and MAX3172/MAX3174 trans-
ceivers will all be placed in X.21 DCE mode.
Fail-Safe
The MAX3172/MAX3174 guarantee a logic HIGH
receiver output when the receiver input is shorted to
GND or when it is connected to a terminated transmis-
sion line with the driver disabled. The V.10 receiver
threshold is between +25mV and +250mV. If the V.10
receiver input voltage is less than +25mV, R4OUT is
logic HIGH. If the V.10 receiver input is greater than
+250mV, R4OUT is logic LOW.
The V.28 receiver threshold is between +0.8V and
+2.0V. If the V.28 receiver input voltage is less than
+0.8V, R4OUT is logic HIGH. If the receiver input is
greater than +2.0V, R4OUT is logic LOW. If the driving
transmitter is disabled or disconnected, the receiver
’
s
input voltage is pulled to zero by its internal termination.
With the receiver thresholds of the MAX3172/MAX3174,
this results in a logic HIGH.
Applications Information
Older multiprotocol cable termination implementations
have been constructed using expensive relays with dis-
crete resistors, custom cables with built-in termination,
or complex circuit board configurations to route signals
to the correct termination. The MAX3172/MAX3174 pro-
vide a simple solution to this termination problem. All
required termination configurations are software selec-
table using four mode-control input pins (M2, M1, M0,
and DCE/
DTE
).
V.11 Termination
For high-speed data transmission, the V.11 specifica-
tion recommends terminating the cable at the receiver
