Suggestion for high-speed ADC recommended for new design

Question

Hello, 
 we are currently designing a system based on a high-speed ADC + FPGA. 
 We need to select a 14 bit ADC with a sample rate >= 80 Msps and parallel (CMOS or LVDS) interface. 
 We came across the AD9649, AD9444, AD9255 and others. 
 Which AD component(s) are recommended for new designs? 
 
 Thank you and best regards, 
 AC

Hi AndClarke 
 Both ADC are capable of 80 MSPS sampling rate. 
 AD9648 is a Dual, 14-bit ADC with a minimum of 10 MSPS sampling rate with DCS Disabled (20 MSPS with DCS Enabled), and an output logic level of 1.8 V parallel CMOS or LVDS are supported. 
 
 While AD9642 is a Single, 14-bit ADC with a 40 MSPS sampling rate, and an output logic level of 1.8 V parallel LVDS.)
