TX73L64 is a highly integrated, high-performance transmitter device for ultrasound imaging system. The device has total 64 pulser circuits, 64 transmit/ receive switches (referred as T/R or TR switches), 32 LNA circuits, and supports on-chip beamformer (TxBF). The T/R switches also perform a 2:1 multiplexing operation to multiplex inputs of 2 channels to 1 LNA. The device also integrates on-chip floating power supplies that reduce the number of required high voltage power supplies.

TX73L64 has a pulser circuit that generates three-level high voltage pulses (up to ±100 V) that is used to excite multiple channels of an ultrasound transducer. The device supports total 64 outputs. The maximum output current is 1A.

Device can be used as a transmitter device for many applications like ultrasound imaging, non-destructive testing, SONAR, LIDAR, marine navigation system, brain imaging systems and so on.
