SN65LV1021/SN65LV1212- SN65LV1023/SN65LV1224
10:1 Serializer/Deserializer Evaluation Board (EVM)
ABSTRACT
This application report focuses the use and construction of a Serializer/Deserializer evaluation module
(EVM) constructed to evaluate the characteristics of SN65LV1021/SN65LV1212 Serializers, and
SN65LV1023/SN65LV1224 Deserializer devices. This document provides guidance on proper use by
showing possible device configurations and test modes. It also provides design, layout, and schematic
information, including specific construction recommendations. Information in this guide can be used to
assist the customer in choosing the optimal design methods and materials in designing a complete
system.
