Designs with antenna connectors that require conducted ETSI compliance at 64 MHz should insert an LC resonator in front of the

antenna connector. Use a 1.6-nH inductor in parallel with a 1.8-pF capacitor. Connect both from the signal trace to a good RF ground.

ANT OVERVIEW

ANT is a proven ultralow-power wireless protocol operating in the license-free 2.4-GHz ISM band. It has been

specifically designed to target battery operated devices that require years of battery life (often on a single coin

cell) without sacrificing the robust features expected of a mature wireless protocol. These features include

sophisticated co-existence mechanisms, practical topologies that go beyond simple peer-to-peer or star, easy

proximity-based pairing methods, and the seamless transfer of bulk data from one coin-cell-operated device to

another. Combined, these features enable products that are easy to use and quickly adopted by the end user.

ANT is also the fundamental building block of ANT+, which further enhances the user experience by allowing

manufacturers to create interoperable wireless devices based on ANT+ device profiles.

ANT provides for an easy development and integration experience. By fully integrating the lower four layers of

the OSI stack onto a single chip, designers can focus on their applications and not the wireless protocol. This

enables quick development cycles, fast time to market, and lower BOM costs.
