Functional description
Carrier frequencies
ST7538Q is a multi frequency device: eight programmable Carrier Frequencies are available
(see
Only one Carrier could be used a time. The communication channel could be varied during
the normal working Mode to realize a multifrequency communication.
Selecting the desired frequency in the Control Register the Transmission and Reception
filters are accordingly tuned.
