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

Applications
• Analog satellite broadcast tuners (BS/CS)
• Digital satellite broadcast tuners (DSS/DVB, etc.)
