FUTV3503C ATSC-T Modulator 8-VSB to RF modulation(2*ASI/2*SMPTE 310M input,RF ontput,ATSC 8VSB modulation)with Network management

R: V20150918-14-22 Data sheet  

 

Input:ASI   Output:DVB-C  



Overview



FUTV3503C ATSC-T modulator is FMUSER’s newly designed product supporting ASI and SMPTE-310 input. After modulating the inputting signals through ATSC 8-VSB, it can output RF signals with the range between 40~960MHz. In other words, FUTV3503C 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
•Support ATSC 8VSB modulation
•Support 2ASI, 2 SMPTE 310M, 1 external 10Mhz reference clock and 1 RF input
•RF output frequency range: 40MHz~960MHz,1Hz stepping
•Support RS coding, interleaving and Trellis coding
•Transmission 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.
•LCD/Keyboard and net management, support SNMP/NMS
