AD8146/AD8147/AD8148
Figure 39 illustrates the frequency response of the pre-emphasis
network.
Figure 40 illustrates the frequency response of the pre-emphasis
circuit cascaded with the cable compared with that of the cable
alone. It can be seen that the overall response is flat to within
±0.4 dB. The ±0.4 dB ripple in the response is due to the fact
that the pre-emphasis network is linear, comprised of two real-
axis pole/zero pairs, and the cable response is nonlinear.

EXPOSED PADDLE (EP)
The 24-lead LFCSP has an exposed paddle on the underside of
its body. To achieve the specified thermal resistance, it must
have a good thermal connection to one of the PCB planes. The
exposed paddle must therefore be soldered to a pad on the top
of the board that is connected to an inner plane with several
thermal vias. The AD8147/AD8148 use the paddle as a ground
reference; therefore, for these parts, the PCB plane used must be
the ground plane.
