Description
The CXA3108AQ is a monolithic IC that down-
converts 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 I
2
C protocol
On-chip high voltage drive transistor for charge
pump
Applications
Analog satellite broadcast tuners (BS/CS)
Digital satellite broadcast tuners (DSS/DVB, etc.)
Structure
Bipolar silicon monolithic IC
L-band Down Converter IC with On-Chip PLL
40 pin QFP (Plastic)
