FPGA board selection

Hi,

I am trying to design a FPGA board to sample received ultrasound signals.

The voltage signal range is around -100~100mV from PZT element.

Could you recommand me a FPGA board with ADC?

The desirable specs are :

Number of Channels : 8~16 channels

ADC : 10~12 bits, larger than 80Mhz sampling rate

FPGA interface to PC : USB 3.0 (2.0 is ok, but larger bandwith is needed to transfer sampled data in real-time)

External trigger enable to initiate sampling.

Transmit beamforming (optional)

Thanks.
