Philips Semiconductors Unveils Compelling Three-Chip Solution for Digital Satellite Broadcast Set-Top Boxes.SUNNYVALE, Calif.--(BUSINESS WIRE)--March 12, 1998--Philips Semiconductors today announced a three-chip solution for digital satellite broadcast set-top boxes that reduces the number of ICs required for QPSK (Quadrature Phase Shift Keying) A phase modulation technique that transmits two bits in four modulation states. See PSK and phase modulation. down-conversion and demodulation from five ICs to only three. Based around the company's first ever TDA TDA Texas Department of Agriculture TDA Trade and Development Agency TDA Transportation Development Act TDA Tax Deferred Annuity (commonly known as TSA) TDA Tienda (Spanish: store) 8060 Zero-IF Down Converter, the chipset can handle any DVB (Digital Video Broadcasting) An international digital television (DTV) standard that is the European and Far Eastern counterpart of the North American ATSC standard. or DSS (1) (Digital Signature Standard) A National Security Administration standard for authenticating an electronic message. See RSA and digital signature. (2) (Digital Satellite S broadcast in the 950 MHz to 2200 MHz frequency band. The new three-chip offering also reduces component costs, assembly costs, PC board real estate and potential IF coupling and leakage by eliminating the need for intermediate frequency components such as an IF oscillator oscillator Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air , IF mixer and SAW filter. The result is significantly better performance at a cost of 20% to 30% lower than existing solutions. "The Zero-IF principle used in this new chip-set is a major breakthrough in digital satellite tuner design," said Philippe Hermant, product marketing manager, Philips Semiconductors. "It not only reduces set-top box manufacturing costs but also eliminates one of the most problematic areas for design engineers." For complete QPSK down-conversion/demodulation of the satellite dish output into an M PEG-2 data stream, the TDA8060 only needs to be combined with a TDA8043 or TDA8044 QPSK Demodulator/Forward Error Corrector IC and a low-cost TSA TSA See tax-sheltered annuity (TSA). 5512 PLL PLL - phase-locked loop Frequency Synthesizer, making it a true 3-chip solution. Non-critical low-pass filtering is all that is required in the I and Q channels between the TDA8060 and the TDA8043/TDA8044, making the entire circuit alignment-free during manufacture. No 6-bit dual A/D converter chip is required either, as this functionality is integrated into the TDA8043 and TDA8044. Between them, these two demodulator See demodulate. Demodulator A device used to recover the original modulating signal from a modulated wave. A demodulator is also known as a detector. ICs cover worldwide DVB requirements. To ensure a simple design-in process for this unique chip set, Philips Semiconductors provides tuner manufacturers with a complete reference design in the form of the OM5712 Digital Satellite Tuner Module. The chip-set and the tuner module, both of which are designed and manufactured at Philips Semiconductors' facility in Caen, France, are available now. The individual components of the chip-set are priced as follows, when purchased in quantities of 100,000: the TDA8060 is $3.00; the TDA8043/TDA8044 is $11.40; and the TSA5512 is $0.73.
