ON Semiconductor LV25810PEB-6156H

Description
The LV25810PEB is a DSP tuner LSI that adopts LowIF. This IC has realized not only the significant reduction of external parts compared to the existing model by integration but also the reconfiguration of specification according to customers' needs by setting and controlling the software of the microcontroller, in which the constant is programmable. Therefore, this IC curbs the total cost and realizes a tuner that corresponds to the onboard type. This LSI implements a serial bus (FC) I/F, which realizes a reduction of the communication line with the microcontroller. In mass production, it is effective to prevent troubles related to line layout and to reduce the area of the system main board. In addition to radio basic functions, LV25810PEB integrates a new original CMA circuit to enhance multipath noise rejection features. Also, LV25810PEB includes an HD Radio decoder interface.
