Features
1. Description
The ATR4289 is an integrated circuit in BiCMOS technology for frequency synthesiz-
ers. It performs all the functions of a PLL radio tuning system and is controlled by a
2-wire bus. The device is designed for all frequency synthesizer applications in radio
receivers, as well as for radio data system (RDS) applications.
