TIMING NOTES
1. The ADS-945 is an edge-triggered device requiring no additional external
timing signals. The rising edge of the start convert pulse initiates a con-
version.
2. A start convert pulse of 50ns is recommended when sampling at 10MHz.
3. The falling edge of the subsequent start convert pulse (N+1) or the rising
edge of the N+2 pulse can be used to latch data from conversion N (1
pipeline delay).
