Sonar applications such as fish finding, and so on require a slightly different set of specifications as compared to the conventional medical imaging applications. Sonar applications typically use a low frequency transmit wave (50-150kHz) for high depth imaging. The transmit pulses are also quite long, ranging from several µs to few ms for higher energy transfer. Depending on the application and resolution required, chirp waveforms are also commonly used for increased axial resolution and depth discrimination.

For such applications, TX75E16 is an option if the on-chip beamforming capabilities are sufficient for the required application. With a maximum clock frequency support of 320MHz, TX75E16 offers resolution for chirp waveforms. The device also supports large pattern memory per channel along with multiple pattern compression techniques to reduce the memory requirement for a complex transmit pattern common in sonar applications.
