2.2.5 TDC1000-C2000EVM Hardware Configuration

Channel 1 (TX1/RX2) was configured for the 220 kHz transducer:

Channel 2 (TX2/RX1) was configured for the 1 MHz transducer:

  • Default out-of-box band-pass and LNA feedback values were used.
  • The EVM 8 MHz MEMs oscillator served as the TDC1000 input clock source, JP1 pins 1-2 shorted.
