URRENT CONSUMPTION
The control bit values for selection of each mode and typical current consumption for the modes are shown in Table 3.
When clock out is activated there is an extra power demand proportional to the programmed output level (see Table 4
for examples). When bit Xtal high = 0 (oscillator is in low current consumption mode), the crystal in use must have losses
less than 20
to ensure oscillator start-up.

FM receiver
The FM receiver (see Fig.3) has a single frequency conversion architecture with integrated image rejection mixer that
makes an external RF filter unnecessary. The Side Band Select (SBS) feature allows choice of frequency for RXLO to
be in or out of the ISM band allowing use of the same IC type for both base station and handset. IF channel filtering
(a compromise between price and performance) can be implemented simply using two or three external 10.7 MHz filters.
The integrated FM PLL demodulator with limiter decreases significantly the number of pins and external components
required.
