The FM receiver part
FM RECEIVER
The FM receiver has the programmability to operate for all country channels, including the 25 U.S. channels, without the
need for external switching circuitry (see Fig.3).
The gain and input impedance of the LNA are programmable. The LNA also includes a programmable capacitance to
avoid external manual fine tuning.
