... T4227 Design Hints for the Ferrite Antenna The bar antenna is a very critical device of the complete clock receiver. Observing some basic RF design rules helps to avoid possible problems. The IC requires a resonant resistance kW. This can be achieved by a variation of the L/C-relation in the antenna circuit not easy to measure such resistances in the RF region ...
