2.3.4 THVD8000 Schematic

Figure 2-7 shows the schematic overview of the THVD8000.

TIDA-010935 THVD8000 Schematic Figure 2-7 THVD8000 Schematic

The selection between transmitting and receiving phase is handled by the THVD8000 as depicted in Figure 2-7. The FSET pin provides the carrier frequency, chosen by the TMUX between 125 kHz, 500 kHz, 2 MHz, and 5 MHz.

The MODE pin is responsible of setting the receiving (set low) and the transmitting (set high) phase, if the TX phase is active the signal is taken as input from the pin D, if the RX phase is active the R pin is taken as output.
