... Datasheet : ADC1020 – C35 SYMBOL THEORY OF OPERATION The AD1020 is a 10-bit ADC capable of sampling at 20 MS/s. It uses a fully differential pipelined architecture with 1.5-bit per stage and digital error correction to achieve improved linearity performance. A dedicated wide-band input sample-and-hold amplifier (S/H) is built-in to provide low-jitter, sub-sampling capability with inherent frequency down-conversion and, optionally, Revision C, 07 ...

... The converter operates with fully-differential or single-ended inputs. The best performance of this ADC is reached for fully-differential inputs. Single Ended Mode To use the ADC1020 as a Single Ended Converter the input VINN must be connected to VCM. In this case the ADC performs a single-ended to fully-differential conversion. The second input VINP should be balanced around VCM. ...

... Datasheet : ADC1020 – C35 FUNCTIONAL BLOCK DIAGRAM MDAC S/H 1 FLASH Clk D8 TIMING DIAGRAM The sampling rate of the AD1020 is defined by the frequency of the CLK signal. The input signal voltage of the ADC is sampled in the falling edge of CLK. As the conversion stages operate in a staggered fashion in alternate phases of CLK, the duty-cycle of this signal must be 50%. The results are latched in the output register on the falling edge of CLK, with a latency of 5 CLK periods ...
