(1) 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.
