The Quad ADC is constituted by four 8-bit ADC cores which can be considered independently (four-
channel mode) or grouped by two cores (two-channel mode with the ADCs interleaved two by two or
one-channel mode where all four ADCs are all interleaved).
All four ADCs are clocked by the same external input clock signal and controlled via an SPI (Serial
Peripheral Interface). An analog multiplexer (cross-point switch) is used to select the analog input
depending on the mode the Quad ADC is used.
The clock circuit is common to all four ADCs. This block receives an external 2.5 GHz clock (maximum
frequency) and preferably a low jitter symmetrical signal. In this block, the external clock signal is then
divided by two in order to generate the internal sampling clocks:
• In four-channel mode, the same 1.25 GHz clock is directed to all four ADC cores and T/H
• In two-channel mode, the in-phase 1.25 GHz clock is sent to ADC A or C and the inverted 1.25 GHz

clock is sent to ADC B or D, while the analog input is sent to both ADCs, resulting in an interleaved
mode with an equivalent sampling frequency of 2.5 Gsps
