Outline
COL5441B is a cost effective integrated 4 in 1 QAM modulator supporting multiplexing and scrambling. This device supports maximum 16 ASI input, after 4 multiplexer and 4 scrambler process, then gives 4 carriers output (4 adjacent frequency output by 1 RF port). It’s ideal for processing ASI input data from different devices and giving RF output by only one device. With its powerful function, it can reduce the operator business cost effectively.
Features:
l Support 16 ASI input
l Fully support EN300 429/ITU-T J.83A/B/C
l Support PSI/SI editing and inserting
l 4 MUX,4 SCR, 4 QAM embedded
l Support 4 simulcrypt CA
l Support accurate PCR adjusting
l 4 Frequency output with excellent MER≥40dB
l Support 16/32/64/128/256QAM
