U4256BM-R General Description
The U4256BM-R is a synthesizer IC for FM receivers and an AM up-convertion system in BICMOS technology. Together with the AM/FM IC T4258 or U4255BM, it performs a complete AM/FM car radio front-end, which is recommended also for RDS (Radio Data System) applications. It is controlled by a 3-wire bus and also containsswitches and Digital to Analog Converters (DACs) for software-controlled alignment of the AM/FM tuner. The U4256BM-R is the pin-compatible succesor IC of U4256BM-N.
U4256BM-R Features
·Reference Oscillator up to 15 MHz (Tuned)
·Oscillator Buffer Output (for AM Up/Down Conversion)
·Two Programmable 16-bit Dividers
·Fine-tuning Steps Possible
·Fast Response Time due to Integrated Loop Push-pull Stage
·3-wire Bus (Enable, Clock and Data; 3V and 5V Microcontrollers Acceptable)
·Four Programmable Switching Outputs (Open Drain)
·Three DACs for Software Controlled Tuner Alignment
·Low-power Consumption
·High S/N Ratio
·Integrated Band Gap ¨C only One Supply Voltage Necessar
