DTT System IP To RF Modulator 4 Ch ASI To RF DVB - T2 Modulator COL5602

COL5602 DTT system for Africa 4 Ch ASI to RF DVB-T2 Modulator

Outline

COL5602 is a single-channel DVB-T2 modulator. Ithas two ASI inputs, and provides one IP signal input interface for DVB-T2 SFN/MFN. It can receive signal in both standard TS format and T2-MI format, and outputsone DVB-T2 (30MHz～900MHz) modulated signal after channel coding, interleavingand modulation. It operating parameters can be configured locally or remotely via DVB-T2 gateway. COL5602’s output signal can be directly connected with power amplifier to constitute a digital terrestrial transmitting station.
