Register Listing
Bypassing and Layout
Considerations
MegaQ™ requires a dedicated ground plane in
order to function properly. For 2-layer boards, pour a
quarter-inch ground plane extending around the device
on both the top and bottom layers. Ensure that the
ground plane on the bottom layer is a solid plane with
no traces cutting through it. Bypass capacitors must be
placed as close as possible to the device in order to
ensure good performance at longer lengths of
equalization. Ensure that the ground connections for the
bypass capacitors connect directly to the same uniform
ground plane described above.
General PowerPAD Design Considerations
The thermal pad must be connected to the ground plane
for heat dissipation. Figure 50 is an example of how to
use vias to remove heat from the IC.
The thermal pad is electrically connected to GND through
the high resistance IC substrate. We recommend you fill
the thermal pad area with vias. The via array should be
centered in the thermal pad and placed such that the
center on center spacing is 3x the via radius. Vias should
be small, but large enough to allow solder wicking during
reflow. Connect all vias to ground. It is important the vias
have a low thermal resistance for efficient heat transfer.
Do not use “thermal relief” patterns. It is important to

have a solid connection of the plated-through hole to
each plane.
Power Dissipation
The maximum power dissipation allowed in a package is
determined according to Equation 1:
PD
Where:
The maximum power dissipation actually produced by an
IC is the total quiescent supply current times the total
power supply voltage, plus the power in the IC due to the
load, or:
for sourcing use Equation 2:
PD
for sinking use Equation 3:
PD

*Signal must be missing for at least 1ms in order to
trigger a re-equalization.
** In Manual Length mode the polarity corrector is
disabled and the polarity must be set using the
INVERT bit or pin.
Note: The FREEZE pin must be tied to ground/a logic
low for this function to work correctly.
