Single-chip COFDM Demodulator for Digital Terrestrial Receivers STMicroelectronics, worldwide leading supplier of MPEG2 digital video ICs, offers new advanced end-to-end solutions for interactive set-top boxes. With an OMEGA single-chip decoder, the STV0360 COFDM demodulator forms a complete chipset for digital terrestrial platforms. Digital Terrestrial Platform Flash The STV0360 is a high performance single-chip COFDM (Coded Orthogonal Frequency-Division Multiplex) demodulator with built-in A/D converter. It performs all the demodulation functions required to extract the MPEG transport stream from the tuner IF output and connects seamlessly to ST’s industry standard STi55xx OMEGA set-top box decoders. The STV0360 provides, amongst others, the following key features: • Compliance with DVB-T (ETS 300 744) and NORDIG II specifications • Inputs for direct IF, eliminating the need for a down-converter in the tuner • Adaptative channel correction in both time and frequency, providing excellent performance, even in the presence of noise or significant Doppler shift • Dual Automatic Gain Controller (AGC) to seamlessly interface with all tuners characteristics • Support for 2K/8K carrier detection modes • Automatic mode, puncture rate and guard detection • Advanced automatic pre-echo problem resolution (SFN mode) – supporting 6, 7 and 8 MHz channels • Fast scanning acquisition mode • Embedded impulsive noise reduction • Tri-state parallel and serial data output • Very low power consumption (less than 500 mW) • PGA (Programmable Gain Amplifier ) increasing flexibility to enhance tuner power matching • Additional A/D converter to directly monitor the input level of the new generation of tuners • Small 64-pin TQFP package SDRAM Digital audio multi channel Tuner STV0360 STV0700 Common Interface OMEGA TV monitor VCR Single Chip COFDM Demodulator AGC1 AGC2 COFDM Core PGA PLL MONITORING FEC BER Monitoring Viterbi Decoder Constellation Display De-Interleaver Supply Control PIO I2C ADC Lock Indicator Display Reed-Solomon Decoder Descrambler Lock Transport Stream EVAL0360 Development Platform A comprehensive evaluation platform is provided with the STV0360 single-chip COFDM demodulator, including a scalable evaluation board and a complete set of software drivers. The platform significantly reduces the time to develop customized, feature-rich terrestrial set-top boxes and accelerates product introduction cycles. An attractive very low-cost demo platform based on the STV0360 and STi5518 chipset (code-named ‘Digital Converter Brick’) is exhibited as a show-case package with optimized memory footprint and EPG software based on STAPI DVB reference tree. This design is scalable and ready to support HDD and middleware such as MHEG-5, MediaHighway or OpenTV. Schematics and Bill of Materials of this demo board are available on request. Software Environment STMicroelectronics provides a complete fully-supported and documented software package for the STV0360 COFDM, giving an easy access to all the device features, including an in-depth performances analyser. • Full access to circuitry ressources • User-friendly graphical environment • Windows 98/2000/NT compatible • STAPI drivers for the OMEGA devices • Performances optimization tools: - application debugger - in-depth analysis of performances with BER, SNR, echos, constellations, statistics Lock Interpolator Symbol Channel correction Pilot Processor Symbol De-interleaver Carrier Rec.
