2. Straight mode (See Application Circuits 1-(4), (5) and (6).)

Set the SELECT pin to GND for this mode. In this mode, data output can be obtained in accordance with the

clock frequency applied to the A/D converter for applications which use the clock applied to the A/D converter

as the system clock.

The A/D converter can operate at Fc (min.) = 125MSPS in this mode.

Digital input level and supply voltage settings

The logic input level for the CXA3276Q supports ECL, PECL and TTL levels.

The power supplies (DVEE3, DGND3) for the logic input block must be set to match the logic input (CLK and

reset signals) level.
