STMicroelectronics, supplier of silicon chips for set-top boxes (STBs), announced the STV0362 coded orthogonal frequency-division multiplexing (COFDM) demodulator-a chip designed to perform front-end processing of terrestrial digital TV transmissions throughout Europe.
It is said that the STV0362 has an operating power consumption of less than 250mW (typical), making it for portable DVB-T applications, in addition to its main use in NorDig-compliant STBs and iDTV (Integrated Digital TV) sets. The power and cost saving breakthrough results from the use of ST’s advanced CMOS090 design platform, which is based on 90nm CMOS process technology.
The STV0362 can manage signals containing such echoes by synchronizing up to 260 microseconds outside the guard interval. Doppler shifted signals, seen in mobile applications or where an echo is received from a moving object, are detected and processed in accordance with NorDig requirements, using adaptive channel correction in both time and frequency.
