This block corrects for the time skews among the interleaving sub-RF-ADCs. Any residual difference can result in spurious signal at +/-fin + (k/N)*Fs, where Fs is the sample rate of the RF-ADC, N is the number of sub-RF-ADCs, fin is the frequency of the input signal. The TSCB requires the presence of an input signal. The minimum power of this input signal is -40 dBFS. This block should be in the freeze mode whenever the input signal power drops below -40 dBFS for longer than 100 μs.
