TRANSMITTER FUNCTIONAL DESCRIPTION
MC33493 is a PLL tuned low power UHF transmitter. The different modes of operation are controlled by the
microcontroller through several digital input pins. The power supply voltage ranges from 1.9V to 3.6V allowing
operation with a single lithium cell.
PHASE LOCKED LOOP AND LOCAL OSCILLATOR
The VCO is a completely integrated relaxation oscillator. The Phase Frequency Detector (PFD) and the loop filter
are fully integrated. The exact output frequency is equal to: fRFOUT = fXTAL x [PLL Divider Ratio]. The frequency
band of operation is selected through the BAND pin.
Table 1 provides details for each frequency band selection.
