Hello,
Does ADS4122 support direct clocking or does the asic alter the clock signal internal (e.g. PLL, DCS etc.)? In figure 93 of datasheet, there is an input buffer with a branch directly to the sampling circuit visible, while the second connection goes to an internal clock generator.
Is this clock generator just for sync of the output clk needed and for proper timing of the SC circuits needed (charge injection etc. ) or is there a complete clock recovery?
