Description
LAPIS 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.
ML7137 is OFDM demodulate and error correction LSI which receives 2-branch diversity for full segment broadcast.
ML7147 is single-chip LSI that integrates the RF-CMOS tuner newly developed in addition to the OFDM demodulator.
ML7107 is for the OFDM demodulator for one-segment broadcasting and digital radio (one-segment and three-segments reception).
Feature
• ML7137
OFDM demodulator LSI supporting full-segment and one-segment .
- Compliant to full-segment and one-segment broadcasting of ISDB-T(ARIB STD-B31) digital terrestrial television broadcasting.
- Even in the Doppler shift by fast motion or the rapid electric-field fluctuating environment by the trough between buildings, 2 branch substitution diversity algorithm developed originally by LAPIS Semiconductor implements stable reception. Inband noise-removal function is installed, and not only the field reception performance are improved but also the countermeasure to spurious, which poses a problem at the time of set development, becomes easy.
• ML7147
Single-chip LSI that integrates RF tuner and OFDM demodulator
- Compliant to the one-segment broadcasting (partial reception of ISDB-T) of digital terrestrial broadcasting (ARIB STD-B31).
- LAPIS Semiconductor developed an original synchronization and equalizing algorithm that realized an superior performance in fast fading environment.
• ML7107
OFDM demodulator LSI supporting one-segment broadcasting and digital radio (one-segment and three-segments reception).
- Compliant to one-segment broadcasting of ISDB-T(ARIB STD-B31) digital terrestrial television broadcasting and ISDB-TSB(ARIB STD-B29) digital terrestrial voice broadcasting.
- LAPIS Semiconductor developed an original synchronization and equalizing algorithm that realized an superior performance in fast fading environment.
Application
