Intersil 

HI3026A

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 HI3026A 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.
