TIDA-00151: Reg Board

Vignesh Ramasamy
Prodigy 30 points
Part Number: TIDA-00151
Other Parts Discussed in Thread: PGA450-Q1, PGA460, PGA460-Q1,

Hi,

     I am very much interested to buy the Board and Ultrasonic Sensor. But I have some few technical doubts in Board. I need to design my machine as one ultrasonic sensor should transmit first and it should received by another ultrasonic sensor, after sometime it should transmit the signal, the another ultrasonic should receiver that signal. Like I need to control the transmit and receive in Board. Kindly provide me the required information.

    Hi Vignesh,

    Yes, the PGA460-Q1 or PGA450-Q1 will be able to achieve this bi-static type of transducer implementation. Bi-static meaning that you can use a single IC to drive an independent transmitter sensor element, while simultaneously monitoring the return on an independent receiver sensor element. You can read more about this type of implementation in section 3.1 "Sonar Configuration" of the PGA460 Ultrasonic Module Hardware and Software Optimization app note ( www.ti.com/.../slaa732 ).

    Alternatively, and depending on the position/location of the transmitter and receiver elements, you can dedicate an independent IC to both transceivers so that either can act as a listen-only, transmit-only, or burst-and-listen type of sensor.

    I recommend that you use the PGA460 due to the improved performance and reduced software/development overhead. We offer a variety of small form factor reference board equivalents to the TIDA-00151, but for the PGA460. This list of reference designs can be found in the Design files section on the following page:
    www.ti.com/.../technicaldocuments

    You will notice there a few options in terms of driver mode (transformer vs half-bridge) and transducer configuration (mono- vs bi-static).
    If you can specify your performance requirements, I can help to make a more specific recommendation:
    1) What is your required range (minimum and maximum)?
    2) What is the application/system use-case?
    3) What is your required field-of-view?
    4) Will the sensors be exposed to dirt/dust/debris/water/ice?
    5) Do you have any space, size, or power constraints? What is your available supply voltage to the ultrasonic module?

    Before skipping to reference design evaluation, I typically recommend users to begin their evaluation/development using the PGA460-Q1 EVM ( www.ti.com/.../boostxl-pga460 ) to firstbecome familiar with the device using the accompanying PGA460-Q1 EVM GUI ( www.ti.com/.../slac739 ).
