Hi all, I need understand the results of a design: spectrometer with 2048 channel and mode interleave.
I understand that the idea of a time-interleaved ADC (TIADC) is to use a system of M parallel channel ADCs, which alternately take samples (time-interleaved sampling). Thereby, the sampling frequency of one channel does not need to fulfill the Nyquist criterion; however, when in the digital domain all samples are merged into one output sequence the overall sampling frequency fulfills the Nyquist criterion. when I synthesized the design with mode interleave, I have 4096 channels in the out, you can to see in the attachments. In 308 and 309 channels the power are 9865259 and 2189. In the 922 an 923 power are 50 an 253520. How is out of ADC blocks with mode interleave? Cheers katty
