SERIAL PROGRAMMING INTERFACE (SDO)
t(OZD) Delay from the falling edge of the 16th SCLK cycle during read operation for SDO transition from tri-state to valid data 1 ns
t(ODZ) Delay from the SCS rising edge for SDO transition from valid data to tri-state 10 ns
t(OD) Delay from the falling edge of SCLK during read operation to SDO valid 1 12 ns
(1) tADC is an exact, unrounded, deterministic delay. The delay can be negative if the reference sample is sampled after the SYSREF high capture point, in which case the total latency is smaller than the delay given by tTX.
(2) The values given for tTX include deterministic and non-deterministic delays. Over process, temperature, and voltage, the delay will vary. JESD204B accounts for these variations when operating in subclass-1 mode in order to achieve deterministic latency. Proper receiver RBD values must be chosen such that the elastic buffer release point does not occur within the invalid region of the local multiframe clock (LMFC) cycle.
(3) tAJ increases because of additional attenuation on the internal clock path.
