L64733/34 Tuner-Receiver Chip Set Integraâ 2000 Solution for Set-Top Box Manufacturers Overview The L64733/34 chip set, a component of the Integra set-top box platform, is a next-generation tuner and channel receiver that provides a highly integrated, high-performance solution for digital satellite broadcast TV. The chip set provides essential tuning and demodulation functions for the set-top platform, enabling a spectrum of applications, ranging from receive-only digital video broadcast to high-speed Internet access, IP telephony, Video-on-Demand and wireless communications. It enables manufacturers to compete in the marketplace by cost-effectively leveraging new digital forms of information and entertainment in the set-top box platform The L64733/34 supports a wide range of worldwide DBS applications. Motherboard or Module Implementation Combining LSI Logic’s market-proven channel technology with an advanced tuner IC in a small, compact design, the chip forms a complete ‘L band to bits’ system, eliminating the need for tuner cans or additional synthesizer chips. As a result, the two-chip solution can be implemented directly on the motherboard or on a module smaller than the size of a credit card. Manufacturers can develop cost-effective solutions for add-on PC cards or multiple digital TV front-ends. LSI Logic’s Two-Chip QPSK Tuner/Demodulator The L64733/34 chip set packs the functionality of multiple components, including the synthesizer, into two compact, highly integrated devices. The solution ensures maximum flexibility, reliability and performance, while reducing costs and delivering world standards compliance. L64733/34 Tuner-Receiver Chip Set Features • • • • • • • DVB-S and DSS compliant 1-45 MBaud solution Handles -20 dbm to -70 dbm input range Two-chip complete receiver function reduces component count Internal baseband variable filters replace discrete-fixed filters Microcontroller enables fast acquisition and false-lock detection LSI Logic also offers a worldwide support organization, with offices located throughout the world and backed by corporate productline and design engineers, to ensure customer success with the company’s set-top box products Tuner IC/QPSK Demod Block Diagram Design and Implementation Flexibility Designed for maximum integration, flexibility and reliability, the L64733/34 can be implemented as a standalone direct conversion satellite demodulation solution for set-top boxes. Or the chip set can be combined with LSI Logic’s SC2000, the other component of the Integra 2000 platform, for a complete three-chip satellite set-top box solution. Technical Description The two chips contain all the functions necessary for satellite QPSK demodulation. The chip set consists of the L64733 zero IF tuner IC, which performs the RF down conversion, and the L64734, which is the QPSK demodulator. The zero IF tuner uses two AGC controls, one in the RF amplifier, the other in the baseband amplifier. The entire range of DBS inputs is covered by this control. The synthesizer function is split between the two devices, with the high-frequency VCO and prescaler residing on the tuner IC. The QPSK chip contains the remaining frequency dividers and tuning control circuitry. A proprietary frequency doubler in the tuner IC enables use of a lower-frequency tank circuit, simplifying board design. Accurate quadrature demodulation is performed, and the baseband I and Q signals are amplified and filtered by adjustable 7-pole Butterworth filters. Automatic DC offset and phase error adjustment are performed by the Tuner IC. The L64734 generates the control signals for the L64733 synthesizer using an on-chip microcontroller to manage the tuning function along with other acquisition and tracking functions. The L64734 also controls the low-pass baseband filters and generates the control voltages for automatic gain control on the L64733. The chip set delivers key technical advantages over previous or three-chip set implementations: • Offers a proprietary frequency doubler, used in the synthesizer, that minimizes board layout effort • Eliminates external IF or baseband filters for lower parts count and higher reliability • Operates from 1-45 Mbaud for worldwide DBS capability Complete Solution for Fast Time-to-Market To accelerate development of set-top box solutions, the L64733/34 is available with a Developer’s Kit, allowing manufacturers to select the option best suited to their target market and application requirements.
