4 Evaluating
Hardware
The EVK is designed for flexible and accurate evaluation of LMH0340 and LMH0341. Evaluation can be
performed using internal or external stimuli.
There is an internal pattern generator implemented in the FPGA that will generate test patterns to verify signal
transmission and signal integrity. The pattern generator can generate various types of SD, HD and 3G SDI static
video patterns.

Standalone Video Generator Tests
In Standalone mode the system performance can be determined by the internal pattern generator. This is done
by connecting the serializer output TX1 on J8 to the deserializer input RX on J13. The loop through output of the
deserializer can be connected to external test equipment such as a WFM700 or an oscilloscope.
