Product Summary
The Q1900C-1N is a viterbi / trellis decoder. It is well suited for many commercial satellite communication networks, including INMARSAT and INTELSAT. The low-cost and high performance of the Q1900C-1N make it ideal for FEC requirements in systems such as direct broadcast satellites (DBS), microwave point-to-point data links, very small aperture terminals, digital modems, digital videl transmission systems, high speed data modems and military and NASA communication systems.
