ELECTRICAL CHARACTERISTICS (continued)

FM Receiver

The FM receivers can be used with either a quad coil or a

ceramic resonator. The FM receiver and 1st LO have been

designed to work for all country channels, including 25

channel U.S., without the need for any external switching

circuitry (see Figure 25.)

(Test Conditions: VCC = 2.6 V, TA = 25°C, fO = 46.61 MHz, fDEV = ± 3.0 kHz, fmod = 1.0 kHz.)
