Manual
Description
This document describes the NCS2220A 8 pin UDFN
package evaluation board. It should be used in conjunction
with the data sheet which contains full technical details on
the device specification and operation. This evaluation
board is offered as a convenience for the customers
interested in performing their own engineering
characterization and performance assessment.
The evaluation board provides a 50 W controlled impedance
environment. The evaluation board is designed to facilitate
a quick evaluation of the device.
This evaluation board manual contains:
• Information on NCS2220A Evaluation Board
• Bill of Materials
Board Lay-up
The evaluation boards are implemented in two layers.
The first layer is the primary signal traces and the device.
The FR4 dielectric material is placed between the first and
second layer. The second layer is the 1.0 oz copper ground
plane, with portion of the ground plane cutout for power.
Board Design
The evaluation board was designed to be flexible (See
Figure 2).
• Inputs
♦ Inputs have place holders for termination resistors to
ground if input signal requires termination
• Outputs
♦ Outputs have a place holder for loads. It can either
be loaded with resistor or capacitor or both or none
at all.
• Power Supply
♦ It can be operated with either single power supply or
dual power supply
− For single power supply – Jumper the V
EE
and
GND together
− For dual power supply – Do not jumper the V
EE
and GND
♦ Both V
CC
and V
EE
have power supply decoupling
capacitors
