DTE-3114

Quad QAM modulator with IP input

DekTec's standalone power-over-ethernet enabled Quad QAM Modulator with IP Input, with advanced time-reconstruction algorithm to overcome IP jitter.
 

Features

• Standalone four-channel QAM modulator with IP (TS-over-IP) inputs and RF output agile over the VHF and UHF band
• Power-over-Ethernet support: No separate power feed required
• Supports IP de-encapsulation and 2D FEC decoding according to SMPTE 2022-1/2
• Removal of IP jitter with programmable size of jitter-tolerance buffer
• LCD status display shows device identifier, bitrate, IP/MAC address and status

Applications

• Small-scale CATV networks
• Cable-network simulator
• QAM test-signal generator

Powering Options

• Through the Ethernet cable using:
  - IEEE 802.3af compatible PoE switch
  - PoE midspan power inserter
• With DTE-PWR2 power adapter

Hardware Limitations

• Channels must be grouped: overall spectrum of the DTE-3114 cannot be wider than 32MHz
• All channels must operate in the same mode and with the same symbol rate
• Not supported:
  - Scrambling of incoming Transport Streams
  - VBR input streams
  - SPTS-to-MPTS multiplexing
   (possible in software with MuxXpert)
