Digital cable tv broadcasting headend modulator qam 4 in 1
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
