Applications
The QAMi5107 is targeted at worldwide cable markets that use ITU-T J83 Annexes A/C or
DVB-C specifications. It provides a single chip solution for the following functions: QAM
demodulation, FEC, transport, descrambling, MPEG a/v decoding, CPU, graphics and
peripherals. Few external components are required to realize a complete STB solution
resulting in very low BOM cost. The QAMi5107 is perfectly suited for digital conversion of
existing analog networks as well as providing advanced security enhancements and system
cost down for designs currently using the QAMi5516 and STx5105/STx5107.
