The present invention relates to a digital beamformer in ultrasound imaging after the process of receiving a digital echo signal. Provided herein is a time multiplexed device and method for beamforming. The device includes an echo data write/read unit, a multi-beam processing unit, a channel data summing unit, and a parameter distributing and synchronizing unit for distributing and synchronizing respective receive parameters to the echo data write/read unit and the multi-beam processing unit through a parameter load bus for each of the beams in the channel.
