  • This monolithic, high-speed transmitter features 16 independent channels with built-in digital beamforming, that generates 5-Level high voltage pulses (up to ±100 V) suitable to excite multiple channels of an ultrasound transducer.

    Each analog channel structure integrates an active RTZ circuit (Clamp) and a T/R switch guaranteeing high OFF isolation between the high-voltage transmitter and the low-voltage receiver when the pulser is transmitting. T/R switches turn ON while receiving echo signals connecting the transducer to the receiver.
    Each channels host two independent half bridges (TX0 and TX1) capable of up to ±2A peak output current in 3 or 5 levels configuration. These half bridges can be put in parallel so to provide 3-level profiles up to ±4A current capability on all 16 outputs.
    Anti-leakage, anti-memory block, thermal sensors and recirculation current protection features complete the architecture.
    Beamforming in ultrasound transmission has traditionally been implemented using analog delay lines. The STHV1600 embeds a digital beamforming mode allowing to program accurate steering of all channels with a resolution as low as 5ns: the signal from each individual transducer element is properly delayed in order to steer the beam in the desired direction.
    Both the digital state machine and serial communication interface can be clocked up to 200MHz with differential or rail-to-rail single-ended embedded options.
    A generous memory allows to store several patterns to drive output channels with desired code excitation. Suitable registers allow handling of all device operations in the proper sequence and managing device diagnostic features.
    Twelve low voltage capacitors are embedded in the package to reduce the external BoM.
    STHV1600 is available in a 10mm x 10mm x 1.4mm 144 pins 0.8mm pitch LFBGA package and is specified for operation from 0°C to 80°C.
