•     Supports Burst or continuous modes, 188 and 204 packet sizes.
•     RF & IF Section are in metal enclosure to noise immunity and high performance
Input
•     DVB-ASI input.
•     DVB-SPI input.
Output
•     RF Output.
•     IF Outputs ( one internally, SMB connector,
      to be used inside the PC to connect to other boards ).
•     DVB-ASI output for monitoring the modulated TS file.
