Several adjustments for the sampling delay and the phase are included in this clock circuit to ensure a
proper phase relation between the different clocks generated internally from the 2.5 GHz clock.
The cross-point switch (analog MUX) is common to all ADCs. It allows to select the analog input that has
been chosen by the user:

• In one-channel mode, the in-phase 1.25 GHz clock is sent to ADC A while the inverted 1.25 GHz
• In four-channel mode, each analog input is sent to the corresponding ADC (AAI to ADC A, BAI to
• In two-channel mode, one can consider that there are two independent ADCs composed of ADC A
• In one-channel mode, one analog input is chosen among AAI, BAI, CAI and DAI and then sent to all
clock is sent to ADC B, the in-phase 1.25 GHz clock is delayed by 90
C and the inverted 1.25 GHz clock is delayed by 90° to generate the clock for ADC D, resulting in an
interleaved mode with an equivalent sampling frequency of 5 Gsps
ADC B, CAI to ADC C and DAI to ADC D)
and B for the first one and of ADC C and D for the second one. The two analog inputs can be applied
on AAI or on BAI for the first ADC (in which case, the signal is redirected internally to the second ADC
of the pair that is, B or A respectively) and on CAI or DAI (in which case, the signal is redirected
internally to the second ADC of the pair that is, D or C respectively)
