TRF1208 Evaluation Module

ABSTRACT

The basic steps and functions that are required to ensure the proper operation and quick setup of the TRF1208-
EVM. This document also includes a schematic diagram, a bill of materials (BOM), printed-circuit board (PCB) 
layouts, and test block diagrams is outlined in this document. Throughout this document, the abbreviations 

EVM, 

TRF1208 EVM

 and the term 

evaluation module

 are synonymous with the TRF1208-EVM, unless otherwise 

noted.
