Layout Recommendation
Decoupling
The DM9081 contains both analog and digital
elements. Separate power pins are provided for the
analog sections, the digital portion of TP line drivers,
the TP line drivers, and the digital core logic. Care
should be taken in board design to minimize coupling

of noise from the power supply and digital logic to the
analog power pins. Decoupling capacitors should be
placed as close to the appropriate V
as possible. Figure 7 shows the recommended
decoupling values for the DM9081 chip.
