Renesas Electronics 

HI3026

Straight Mode (See Application Circuits, Figures 21, 22, 23)

Set the SELECT pin to GND for this mode. In this mode, data out-

put 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) = 100 MSPS in this

mode.

Digital Input Level and Supply Voltage Settings

The logic input level for the HI3026 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.
