Product Description

The DUC***5 & DDC***5 digital up-converter and down-converter have been carefully designed to integrate digital off-air channels into any private cable system. The DDC***5 digital down-converter converts a digital off-air or CATV to a *4 MHz IF signal. The DUC***5 digital up-converter accepts the *4 MHz IF signal and converts it to an 8VSB or QAM output signal on a CATV channel from 2~**5 or an off-air channel from 2~*9. All sub-carrier channels (x.1, x.2, x.3 etc.) are included in the conversion. Each unit occupies a single space in a *2 unit rack chassis allowing up to 6 channels to be integrated in a single chassis occupying 2 rack spaces (3.5). The modulation format (ATSC or QAM) is maintained from the down-converter to the up-converter (ex. QAM to QAM or ATSC to ATSC). These units do not convert digital off-air signals (ATSC) to QAM modulated signals.

DUC***5- Digital Up-Converter

The DUC***5 is specially designed to up-convert a *4MHz RF signal and modulated by a digital signal utilizing QAM modulation. It supplies an output on any channels from *4 to **0MHz. By using the front panel switch can make band-selection much easier.

DDC***5- Digital Down-Converter

The DDC***5 is a quality down converter which designed for translating digital TV signals from the off-air CATV channels to a *4 MHz IF output. It includes a flat passband for minimizing signal deterioration. In addition, it also features low noise figure and low phase noise.
