Power Supply
The device operates from a single +5 Volt supply.
Separate pins for transmit and receive supplies
provide internal isolation. These pins should be
connected externally near the device and decou-
pled to their respective grounds. TV+ must not
exceed RV+ by more than 0.3V.
Decoupling and filtering of the power supplies is
crucial for the proper operation of the analog cir-
cuits in both the transmit and receive paths. A 1.0
μF capacitor should be connected between TV+
and TGND, and a 0.1 μF capacitor should be con-
nected between RV+ and RGND. Use mylar or
ceramic capacitors and place them as closely as
possible to their respective power supply pins. A
68 μF tantalum capacitor should be added close
to the RV+/RGND supply. Wire-wrap bread-
boarding of the line interface is not recommended
because lead resistance and inductance serve to
defeat the function of the decoupling capacitors.
