Is it necessary to buffer the output of the AD9649?

Hello everyone,

 

I want to use the AD9649 to sample a signal with 20MSPS. This ADC has an parallel 14-bit output.

I want to connect this 14-bit output directy to my cyclone IV, but is some articles on the internet

the say it's better to put an buffer/line driver between the ADC (DAC) and the Cyclone IV.

 

Is this true? and if it's true why is it better?

Is it possible to connect my AD9649 directly to my cyclone IV without any consequences?

 

Thanks,

 

Andre
