Design Implementation Flexibility Designed maximum integration, flexibility reliability, L64733/34 implemented standalone direct conversion satellite demodulation solution set-top boxes. chip combined with Logic's SC2000, other component Integra 2000 platform, complete three-chip satellite set-top solution. Technical Description chips contain functions necessary satellite QPSK demodulation. chip consists L64733 zero tuner which performs down conversion, L64734, which QPSK demodulator. zero tuner uses controls, amplifier, other baseband amplifier. entire range inputs covered this control. synthesizer function split between devices, with high-frequency prescaler residing tuner QPSK chip contains remaining frequency dividers tuning control circuitry. proprietary frequency doubler tuner enables lower-frequency tank circuit, simplifying board design. Accurate quadrature demodulation performed, baseband signals amplified filtered adjustable 7-pole Butterworth filters. Automatic offset phase error adjustment performed Tuner
L64734 generates control signals L64733 synthesizer using on-chip microcontroller manage tuning function along with other acquisition tracking functions. L64734 also controls low-pass baseband filters generates control voltages automatic gain control L64733. chip delivers technical advantages over previous three-chip implementations: Offers proprietary frequency doubler, used synthesizer, that minimizes board layout effort Eliminates external baseband filters lower parts count higher reliability Operates from 1-45 Mbaud worldwide capability Complete Solution Fast Time-to-Market accelerate development set-top solutions, L64733/34 available with Developer's Kit, allowing manufacturers select option best suited their target market application requirements. provides hardware software components shorten development cycles ensure fast time-to-market.
