2.EN50083 ASI and SMPTE 310M interface standard
3.10MHz reference clock input

 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.

 

Features:

• Full complying with ATSC A/53 standard
• Constellation mapping: 8-VSB
• EN50083 ASI and SMPTE 310M interface standard
• Dual channel DVB-ASI and SMPTE-310M input, automatic switch-over and hot backup
• RF range: 40MHz~860MHz,1Hz stepping
• Front panel and IP long distance control
• RS coding, data interleaving, Trellis coding
• Channel bandwidth: 6MHz
• Supports adaptive linear digital pre-distortion (DPD)
• Supports adaptive non-linear digital pre-distortion (DPD)
• Adopts constant-temperature crystal oscillator, the frequency stability can be up to 0.1 PPM
• Excellent RF output performance: EVM, MER, SNR, shoulder level and etc.
• Remote maintenance, monitoring and software upgrading
• NMS, Keyboard and LCD operation
