STV0361

STV0360/0361 COFDM demodulators IC for terrestrial TV set-top box DATA BRIEF DESCRIPTION STMicroelectronics complements the world leading range of MPEG-2 decoders with a range of COFDM demodulators for digital terrestrial applications. The STV0360 and STV0361 demodulators are high performance COFDM (Coded Orthogonal Frequency Division Multiplex) demodulators with built in A/D converters. They perform all the demodulation functions to extract the MPEG-2 transport stream from the tuner input. Figure 1. Package/ 64-pin TQFP xxxx Figure 2.
