ATSC-T digital modulator /8VSB modulator for American market

 

 

Outline

NDS2403 ATSC-T modulator is a modulator designed fully complying with American ATSC A/53 standard. This device supports DVB-ASI and SMPTE-310 input, after modulating the inputting signals through ATSC 8-VSB, it can output RF signals with the range between 40~860MHz. In other words, this NDS2403 ATSC-T modulator supports the coding and modulating mode under ATSC-T A/53 standard. Additionally, the system of this device can be on line controlled and upgraded through network, which can be widely used in ATSC-T digital broadcasting network setup and the testing for ATSC-T set top box design.
