TUSTIN, CALIF. TDK Semiconductor Corp. has introduced a coded orthogonal frequency-division multiplexing (COFDM) demodulator/FEC circuit that meets the ETSI specification for European digital terrestrial television broadcasting (DVB-T).
Tim Jackson, vice president of TDK Semiconductor's multimedia business unit, said the company intends to provide a full range of mixed-signal ICs for set-top box applications. TDK's 5610 was designed primarily for the European market. Jackson said a future version is planned for Japan ISDB-T applications.
The part offers both analog-to-digital conversion at an IF input frequency of 4.5 MHz and complete processing of COFDM modulated signals. It includes frequency and time acquisition, 2k and 8k FFT, pilot processing and channel equalization and OFDM demodulation.
Jackson said the chip performs Viterbi and Reed Solomon forward error correction to provide an MPEG-2 transport stream output. The design also includes options for status monitoring and control of an external tuner module via I2C or three-wire pass-through. Samples of the part will be available in October. Production is planned for November. The part comes in an 80-pin MQFP (an 80-pin TQFP is planned for next year) and is priced at $17 in 10,000-unit quantities.
