CXA3108AQ

CXA3108AQ L-band Down Converter IC with On-Chip PLL Description The CXA3108AQ is a monolithic IC that downconverts the L-band (1 to 2 GHz) 1st IF to 2nd IF for satellite broadcast receivers. It integrates a local oscillator circuit, double-balanced mixer, IF AGC amplifier and tuning PLL onto a single chip. This IC supports both analog and digital satellite broadcasts, and achieves reduction in the number of tuner components and smaller size. Features On-chip tuning PLL Supports 2.65 GHz oscillator frequency Noise figure: 12.5 dB typ. (for IF full gain) IF AGC gain variation: 46 dB typ. Wide band IF AGC amplifier (60 to 500 MHz) Two IF outputs PLL supports I2C protocol On-chip high voltage drive transistor for charge pump 40 pin QFP (Plastic) Absolute Maximum Ratings (Ta=25 °C) Supply voltage VCC –0.3 to +5.5 V Storage temperature Tstg –55 to +150 °C Allowable power dissipation PD 730 mW (when mounted on a substrate) Operating Conditions Supply voltage Operating temperature VCC Topr 4.75 to 5.30 –25 to +75 V °C Applications Analog satellite broadcast tuners (BS/CS) Digital satellite broadcast tuners (DSS/DVB, etc.) Structure Bipolar silicon monolithic IC Notes on Handling This IC has a weak electrostatic discharge strength.
