ATSC-T modulator

Specifications

Outline

NDS2403C ATSC-T modulator is DEXIN’s newly designed product supporting 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, NDS2403C ATSC-T modulator supports the coding and modulating mode under ATSC-T A/53 standard. It also supports adaptive non-linear and linear digital pre-distortion (DPD). 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.
