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 23, which is the ground return for
the output buffers. The exposed pad should be connected to the
GND plane using plugged vias so that solder does not leak
through the vias during reflow.
Use of a 22 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 ADN2814 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 24, which supplies power to the
high speed CLKOUTP/CLKOUTN and DATAOUTP/
DATAOUTN output buffers. Refer to Figure 24 for the
recommended connections.
By using adjacent power supply and GND planes, excellent high
frequency decoupling can be realized by using close spacing
between the planes. This capacitance is given by
