1. General Information
1.1 Introduction
This manual provides general information to support the installation and operation of the DB1065
Development Kit, a complete test platform to demonstrate and test the MX465 CTCSS encoder/
decoder.
All trademarks and service marks are held by their respective owners.
1.2 Warranty
The DB1065 hardware has been developed and is provided to help designers develop designs
based on the MX465 CTCSS Encoder / Decoder IC. Every reasonable effort has been made to
provide high quality and performance in pursuit of that goal.
Toward that end, MX-COM, Inc. would value any suggestions to improve the DB1065’s manual
and suggestions concerning the DB1065’s hardware design.
Since experiments and designs are the responsibility of the DB1065 user, MX-COM, Inc.’s liability
