10BIT 80MSPS DAC
PHANTOM CELL INFORMATION
AL1214H
- Pins of the core can be assigned externally (Package pins) or internally (internal ports) depending
on design methods.
The term "External" implies that the pins should be assigned externally like power pins.
The term "External/internal" implies that the applications of these pins depend on the user.

- Maintain the large width of lines as
far as the pads.
- place the port positions to minimize
the length of power lines.

- Do not merge the analog powers with
another power from other blocks.
- Use good power and ground source
on board.
