MAX3172
MAX3174
In Figure 12, the MAX3172 or MAX3174 is used to
implement the resistive T-network that is needed to
properly terminate the V.35 driver and receiver. Internal
to the MAX3172/MAX3174, S1 and S2 are closed to
connect the T-network resistors to the circuit. The V.28
termination resistor (internal to the MAX3170) is dis-
abled by opening S3 to avoid interference with the T-
network impedances.
V.28 Interface
The V.28 interface is an unbalanced single-ended inter-
face (Figure 13). The V.28 driver generates a minimum
of ±5V across the load impedance between A
and C
.
The V.28 receiver has a single-ended input and does
not reject any common-mode differences between C
and C
. The V.28 receiver has input trip points at ±3V.
To aid in rejecting system noise, the MAX3170 V.28
receiver has a typical hysteresis of 0.5V.
Figure 14 shows that the MAX3172/MAX3174 termina-
tion network is disabled by opening S1 and S2. The
MAX3170
s internal 5k
V.28 termination is enabled by
closing S3.
