MOTOROLA RF/IF DEVICE DATA
Evaluation PCB
The evaluation PCB is a versatile board which allows the
MC33411 to be configured to analyze individual operating
parameters or the complete audio transmit and receive
paths.
The general purpose schematic and associated parts list
for the PCB are given in Figure 54. With the jumpers
positioned as shown in the parts list (either shunt or open).
the PCB is configured to analyze complete transmit and
receive audio paths.
Parts lists as ”user defined” can be installed to analyze
other functions of the device. Table 11 lists these devices
along with their respective functions.
