Supertex MD3872 Front-End Ultrasound Receiver Demoboard

Supertex MD3872 Front-End Ultrasound Receiver Demoboard

Supertex MD3872DB1 provides a very useful platform to evaluate this low power and low noise 12-bit resolution ADC ultrasound front-end receiver. Simply connect a 5V power supply to the board and a USB cable to your computer. The on-board MD3872 and T/R switch ICs, TGC, DAC, FPGA, de-serialized LVDS, clock generator, DDR2 data memory, isolated USB interface, JTAG SPI Connector, RS232 serial interface and low noise DC/DC power supplies make a stand alone, desktop 8-channel ultrasound receiver data acquisition evaluation system. Package includes the demoboard power supply cable, USB Cable, software driver and PC user interface software files. All files including the EEPROM file, FPGA configuration file and PC user interface software are available online for updating if necessary.
