Theory of Operation 1.1 General As depicted in Fig.1, the TH72015 transmitter consists of a fully integrated voltage-controlled oscillator (VCO), a divide-by-32 divider (div32), a phase-frequency detector (PFD) and a charge pump (CP). An internal loop filter determines the ...

FSK Modulation FSK modulation can be achieved by pulling the crystal oscillator frequency. compatible data stream applied at the pin FSKDTA digitally modulates the XOSC via an integrated NMOS switch. Two external pulling capacitors CX1 and CX2 allow the ...
Page 5
ASK Modulation The PLL transmitter can be ASK-modulated by applying a data stream directly at the pin ASKDTA. This turns the internal current sources of the power amplifier on and off and therefore leads to an ASK signal at ...

Mode Control Logic The mode control logic allows two different modes of operation as listed in the following table. The mode control pin ENTX is pulled- down internally. This guarantees that the whole circuit is shut down if this ...
