LSI for one-segment broadcasting receiver that realizes an superior performance in fast fading environment and small footprint
--- This LSI is limited to the market in Japan. ---
Description
ML7107 and ML7147 are broadcasting receiver LSI of the one-segment terrestrial digital broadcasting. It achieved the small footprint, the thin type, and low power consumption.
OKI SEMICONDUCTOR developed the original equalizing algorithm, it achieves superior performance in several multipath fading channels. It realizes stable reception even when in Shinkan-Sen moving at speeds up to 300Km/hr and highways.
ML7107 is for the OFDM demodulator for "One-Seg" broadcasting and digital radio(one-segment and three-segments reception).
ML7147 is single-chip LSI that integrates the RF-CMOS tuner newly developed in addition to the OFDM demodulator.
Feature
