ECHO CLOCK MODE-Creating Burst CLK+/- , tMSB • D+/- is Invalid in the CLK+/- Quiet Window – Highlighted in Yellow • The quiet window is effectively set by tMSB and tCLKL • tMSB is the min time from the CNV rising edge until that conversion data is ready to be clocked out – i.e. once tMSB elapses a burst of 16 CLK+/- may be applied for data acquisition • D+/- is output synchronous to DCO+/-
ECHO CLOCK MODE-Creating Burst CLK+/- , tCLKL • The other limit for the quiet window is set by tCLKL • tCLKL timing spec ensures that you have finished clocking the current conversion result prior to the next result being ready internally in the device i.e. you’re not clock results from two different conversions • For the same data result – tMSB and tCLKL are referenced from consecutive CNV rising edges
