    Abstract: A first controller can have a greater number of output lines than a second controller has input lines. The first controller can receive an ultrasonic transducer control signal and provide a first portion of the control signal to the first processor, where the length of the first portion is less than or equal to the number of input lines of the second processor. The first processor can send portions of the control signal to a plurality of second processors. Each of the plurality of second processors can have a number of input lines less than the number of output lines of the first processor. Portions of the control signal can be sent through the output lines of the first processor to the plurality of second processors at substantially the same time.

    Abstract: In order to reduce crosstalk between analog and digital signals, a circuit device includes a vibrator element, a semiconductor device, and a package. In the semiconductor device, an analog pad is provided along a first side facing in a first direction when the semiconductor device is seen in plan view. In addition, a digital pad is provided along aside facing in a second direction opposite to the first direction, that is, a second side facing the first side. In the package, an analog terminal which is connected to the analog pad is provided on a first side of the package facing in the first direction. In addition, a digital terminal which is connected to the digital pad is provided on a second side of the package facing in the second direction.
