Supply current
For the supply current ICCB, see Fig.10.
Using a positive supply voltage
Although the TZA3014 has been designed to use a single
+3.3 V supply voltage (see Fig.11), some care should be
taken with respect to RF transmission lines. The on-chip
signals refer to the various VCC pins. The external
transmission lines will most likely be referred to the
pins GNDA and GNDB, being the system ground.
The RF signals will change from one reference plane to
another when interfacing the RF inputs and outputs.
A positive supply application is very vulnerable to
interference with respect to this point. For a successful
+3.3 V application, special care should be taken when
designing the PCB layout in order to reduce the influence
of interference and to keep the positive supply voltage as
clean as possible.
