Description The CLC5902 Dual Digital Tuner/AGC IC is a two channel digital downconverter (DDC) with integrated automatic gain control (AGC). The CLC5902 is a key component in the Diversity Receiver ChipSet (DRCS) which includes one CLC5902 Dual Digital Tuner/AGC, two CLC5956 12-bit analog-to-digital converters (ADCs), and two CLC5526 digitally controlled variable gain amplifiers (DVGAs). This system allows direct IF sampling of signals up to 300MHz for enhanced receiver performance and reduced system costs.
Applications
| • | Cellular basestations
| | • | Satellite receivers
| | • | Wireless local loop receivers
| | • | Digital communications
