ATR4256-TKQY
ATR4256-TKQY Datasheet
The ATR4256 is a synthesizer IC for FM receivers and an AM up-conversion system in BiCMOS technology. Together with the AM/FM IC ATR4258 or ATR4255, it comprises a complete AM/FM car radio front-end, which is also recommended for RDS Radio Data System applications. It is controlled by a 3-wire bus and also contains switches and Digital to Analog Converters DACs for software-controlled alignment of the AM/FM tuner. The ATR4256 is the pin-compatible successor IC of U4256BM-R.
