High Speed ADC

[qasimmuz]

Hello Everybody,
I'm a new member,
I need an ADC (with 200MHz sampling frequency and 14Bits parallel ) to convert a 50MHz analog signal to digital in order be sent to an FPGA for being I&Q demodulated.

Can anyone suggest me an ADC with mentioned characteristics that is not too complex to use? and a possble clock solution (I have a 3.333 MHz clock in my board)

Thanks
