APPLICATIONS INFORMATION
PCB DESIGN GUIDELINES
Proper RF PCB design techniques must be used for optimal
performance.
Power Supply Connections and Ground Planes
Use of one low impedance ground plane is recommended. The
VEE pins should be soldered directly to the ground plane to
reduce series inductance. If the ground plane is an internal
plane and connections to the ground plane are made through
vias, multiple vias can be used in parallel to reduce the series
inductance, especially on Pin 9, which is the ground return for
the output buffers. The exposed pad should be connected to the
GND plane using filled vias
so that solder does not leak through
the vias during reflow. Using filled vias under the package
Rev. 0 | Page 9 of 12
greatly enhances the reliability of the connectivity of the
exposed pad to the GND plane during reflow.
Use of a 10 μF electrolytic capacitor between VCC and VEE is
recommended at the location where the 3.3 V supply enters the
PCB. When using 0.1 μF and 1 nF ceramic chip capacitors, they
should be placed between the IC power supply VCC and VEE,
as close as possible to the ADN2890 VCC pins.
If connections to the supply and ground are made through vias,
the use of multiple vias in parallel helps to reduce series
inductance, especially on Pin 12, which supplies power to the
high speed OUTP/OUTN output buffers. Refer to the schematic
in Figure 8 for recommended connections.
