CXA3108AQ Overview
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 ponents and smaller size.
CXA3108AQ Key Features
- On-chip tuning PLL
