Figure 13. V.10 Receiver Input Impedance
V.11 (RS422) Interface
A typical V.11 balanced interface is shown in Figure 15. A
V.11 differential generator with outputs A and B with
ground C is connected to a differential receiver with
ground C
', inputs A' connected to A, B' connected to B. The
V.11 interface has a differential termination at the receiver
end that has a minimum value of 100
. The termination
resistor is optional in the V.11 specification, but for the
high speed clock and data lines, the termination is required
to prevent reflections from corrupting the data. The
receiver inputs must also be compliant with the imped-
ance curve shown in Figure 13.
In V.11 mode, all switches are off except S1 inside the
LTC1344A which connects a 103
differential termina-
tion impedance to the cable as shown in Figure 16.
