Transducer Clock Signal Distribution

摘要

An array of ultrasonic transducers can be controlled to produce a steerable beam. Beam steering can be skewed by buffer delays in the distribution of a clock signal. The skew can be at least approximately linearized by distributing the clock signal in a diagonal fashion across an array of buffers corresponding to ultrasonic transducer controllers. Potential error in beam steering that can arise from clock skew can be corrected based on the linear tilt.

1. A method, comprising:
receiving a clock signal at a first board controller buffer of a plurality of board controller buffers; and receiving the clock signal received at the first board controller buffer at a second board controller buffer and a third board controller buffer at substantially the same time from the first board controller buffer, the second board controller buffer being horizontally adjacent to the first board controller buffer and the third board controller buffer being vertically adjacent to the first board controller buffer.
