Demodulator Chip Processes European Digital TV Signals

A COFDM (Coded Orthogonal Frequency-Division Multiplexing) IC, the STV0361 is a demodulator system-on-a-chip (SOC) that performs the front-end processing of terrestrial TV transmissions throughout Europe. It complies fully with European standards including the European Broadcasting Union Digital Video Broadcasting-Terrestrial (EBU DVD-T) specification and the NorDig 1.0.1 standard. The device is designed for digital and hybrid TV sets, terrestrial set-top boxes and digital video recorders. An echo protection capability, which required control from the set-top box in an earlier version of the device, is completely contained in the new version. The device can manage signals containing echoes by synchronizing up to 260 ┬Ás outside the guard interval. Doppler shifted signals, received from a moving object can be detected and processed according to NorDig requirements. The device is supplied in a TQFP64 x64 package. Price is $4.50 each/100,000. ST MICROELECTRONICS, Lexington, MA. (781) 861-2650.
