VCA5807EVM

The VCA5807EVM is an evaluation module for the VCA5807 device. The VCA5807 is an integrated voltage controlled amplifier(VCA) solution specifically designed for ultrasound systems in which high performance and small size are required. The VCA5807 integrates a complete time gain control(TGC) imaging path and a continuous wave doppler(CWD) path. It also enables users to select one of various power/noise combinations to optimize system performance. Therefore, the VCA5807 is a suitable ultrasound analog front end solution not only for high end systems but also for portable systems. The VCA5807 integrates a low power passive mixer and a low noise summing amplifier to accomplish onchip CWD beamformer. 16 selectable phase delays can be applied to each analog input signal. Meanwhile a unique 3rd and 5th order harmonic suppression filter is implemented to enhance CW sensitivity.
