Manufacturer:ALTERA Description:The U4256BM is especially designed for AM up/down converter systems, together with the tuner U4255BM. Due to the integrated DACs, an automatic tuner alignment is possible. All the functions of the U4256BM can be software controlled via a serial 3-wire bus, consisting of Enable, Clock and Data. The format and procedure for the data transfer from the microcontroller is shown in figures 3, 4 and table Data Transfer. All requested data have to be transferred via 16-bit or 24-bit commands. Due to the 8-bit structure, the serial output interface of a microcontroller can be used for the data transfer. The PLL functions can be controlled by 24-bit commands, while the alignment functions are controlled by 16-bit commands. The alignment function control normally is set once by switching on the tuner. Then the tuner automatically will be aligned. The data for alignment are stored in a separate EPROM. Via integrated capacitors it is possible to tune the reference oscillator (this function is controlled via the 3-wire bus). |
