The MD1715DB2 demoboard can drive two transducers as a five-level, two channel transmitter for ultrasound and other applications. The demoboard consists of one MD1715 in a 6x6mm 40-lead QFN package driving 12 high voltage FETs in six TC8020s in one 8x8mm 56-lead QFN package. The CPLD programmable logic circuit 40MHz crystal oscillator generates accurate timing high-speed waveforms on a separate CPL board. There are multiple frequencie and waveform combinations that can be selected as bipolar pulse waveforms. External clock input can be used if the on board oscillator is disabled. The external trigger input can be used to synchronize the output waveforms. There are five push buttons for selecting the demo waveform, frequency, phase, mode selection functions. Color LEDs indicate the demo selection states. Jumpers on board for select the SMA connector to the external loads or the 220pF//1k on board dummy load.
