Demodulator

Socionext’s latest digital TV front-end demodulator LSI supports both DVB and ISDB broadcast systems for worldwide platforms. The SC1502AF-02, for DTV/STB applications, has a dual-type demodulator for terrestrial/cable/satellite broadcasts.

Features

At 7mm x 7mm it is the smallest package size in the world* as a dual-type demodulator LSI. (*According to our research.)
High Connectivity with various tuners.
Demodulator LSI that is compatible with ISDB-S3 and channel bonding technology based on ITU-T J.183.
Output MMT(MPEG Media Transport)/ TLV(Type Length Value) stream that is selectable from TLV format and IP format.

System Configuration

Product Lineup

The SC1502AF2-02 series consists of several products according to the corresponding broadcasting system.
LSI packages and software are common to all products.
