Description
Most of the recently introduced advanced KEELOQ® Encoders, like the HCS362, HCS365, HCS370 and HCS412, have provisions for controlling a multiple stage RF transmitter or a Phase Locked Loop (PLL) circuit. This Technical Brief will provide a few hints on how to interface advanced KEELOQ Encoders to widely adopted PLL ICs, namely Infineon TDA5100 and Temic U2741B.
