[Sony]

Satellite broadcasting using digital modulation first entered service in 1994 in the US, and similar service will begin this year, first in Europe and then in Japan. Thus digital satellite broadcasting is expanding rapidly on a worldwide scale. Sony has now developed a chip set for the tuners of digital satellite broadcast receivers. This chip set, which is introduced here, consists of the CXA3108Q, which takes full advantage of Sonys high-speed bipolar process technology and integrates an oscillator/mixer circuit and a PLL circuit for channel selection on a single chip, and the CXA3038N quadrature detector IC.

CXA3108Q

■ Supports an oscillator frequency of 2.7 GHz

■ High gain and low noise figure

■ On-chip channel selection PLL (Supports both I2C bus* and 3-wire bus systems)

CXA3038N

■ Adjustment-free carrier recovery provided by an on-chip PLL circuit

■ Minimal IQ quadrature error and minimal amplitude error
