This is the Signal specification of AD9208 from Virtual-EVAL
Input : 900MHz(-9dBFS), Clock rate : 3GHz
SNR : 50.7dB SINAD : 50.67dB
But, in the datasheet as below.
in the datasheet, SNR, SINAD are almost 60dBFS.
1. Why does it have difference between Virtual-EVAL & datasheet?
2. Which one is more believable??
3. Maximum(Best) spec of ADC is similar to the result of Virtual-EVAL?
