MOTOROLA RF/IF DEVICE DATA
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.)
