EMC/EMI Test Results
The TIDA-00204 TI design has been tested for EMI according to CISPR 11 / EN55011 Class A radiated
emissions. For EMC immunity, the design has been tested according to IEC61800-3 and IEC61000-6-2 for
ESD, EFT, and Surge with reference to standards IEC61000-4-2, IEC61000-4-4, and IEC61000-4-5,
respectively.
The design is compliant to these standards and exceeds the voltage requirements according to
IEC61800-3 EMC immunity requirements. A summary is shown in the following tables and more details in
the following sections.

Class A is considered when there are less than two consecutive UDP packet losses and no major drop in network utilization.
One UDP packet loss will be tolerated by the system if the following UDP packet is echoed back successfully. The test has been
conducted with a UDP error packet test program at around 5% network bandwidth.

DESCRIPTION
A
The module shall continue to operate as intended. No loss of function or performance even during the test.
B
Temporary degradation of performance is accepted. After the test, the module shall continue to operate as
intended without manual intervention.
C
During the test, loss of functions accepted, but no destruction of hardware or software. After the test, the
module shall continue to operate as intended automatically, after manual restart, or power off, or power on.
