Clock Input Delay Cell (CLKDACTRL)
Figure 3-12. Standalone Delay Cell Tuning Range vs. T
A fine tune delay cell is provided to fine-tune the delay between the clock path and the data path at the
DMUX input. This adjustment may be necessary depending on the sampling rate and/or if there are mis-
alignments or skews on the different input data. However, data path skews should be maintained below
50 ps.
For more information on CLKDACTRL values to be applied, depending on the sampling rate, please
refer to the application note Interfacing ADC with AT84CS001 DMUX, reference 0867.
The delay is controlled by the CLKDACTRL analog control input. It ranges from -275 to 275 ps for CLK-
DACTRL varying from V
the one used in standalone delay cell.
This embedded delay line has characteristics similar to those of the standalone delay cell described in
“Standalone Delay Cell (DAI, DAIN) (DAO, DAON)” above.
This delay depends on the center position of the (CLK, CLKN) clock path in relation to the digital input
data in the DMUX input data paths (I0, I0N) …(I9, I9N) and (IOR, IORN).
