Product Description

Overview

SC-4111 Multiplexer QAM modulator has 2×ASI input and can receive data of DVB transport stream from encoder, multiplexer, DVB gateway, scrambler, video server and other DVB equipment, and then make RS codes, convolution interleaving and QAM modulation channel processing to output RF signal. This MUX modulator adopts a new generation of integrated circuits BCM3034, providing low-power and high index.
