Applications Information
Layout Guidelines
Figure 2 - Example Flow-Through Layout
RClamp3324T is designed to protect 2 high speed
differential pairs. The PCB traces enter and exit each
I/O pin. Ground is connected at pins 5 and 6. Figure 2
is an example of how to route the high speed
differential traces through the RClamp3324T. The
differential impedance of each pair can be controlled
for high-speed interfaces such as HDMI (100 Ohms +/-
15%) and USB 3.0 (85 Ohms +/-15%) while
maintaining a minimum trace-to-trace and trace-to-pad
spacing of 0.125mm when using 0.100mm wide
traces. These are only guidelines. Individual PCB
design constraints may necessitate different spacing or
trace width. Both ground pads should be connected for
optimal performance. Ground connection is made
using 0.254mm diameter filled via-in-pad. The via
should be filled with a conductive paste. This
technique saves board space and eliminates the
capillary effect of a non filled via.
