CXA3266Q and Sony ADC (Demultiplex Mode) Timing : 160MHz specification
The CXA3266Q and CXA3276Q/CXA3286R timings are shown below.
Here, the important timings are as follows.
(The clock cycle is labeled as T.)
For the A/D converters
Clock input vs. reset input
The setup time is T – 1.1ns and the hold time is 0.3ns, satisfying the A/D converter specifications.
For the CMOS LOGIC at the rear end of the A/D converters
A/D converter data output vs. 1/2 clock output timing
The setup time is T – 4.0ns and the hold time is T – 3.0ns. (These timings also include combinations of
three A/D converters from different lots, and are defined for all operating temperatures and all operating
supply voltages. See the CXA3276Q/CXA3286R data sheets for a detailed description.)
For the CMOS LOGIC at the rear end of the A/D converters
DSYNC signal from CXA3266Q vs. 1/2 clock output of A/D converter
The setup time is T – 3.2ns and the hold time is T – 3.7ns.
