CLC5903 Dual Digital Tuner / AGC June 2004 N 0 0 Na t i on a l S e m i c o n du c t o r CLC5903 Dual Digital Tuner / AGC General Overview The CLC5903 Dual Digital Tuner / AGC IC is a two channel digital downconverter (DDC) with integrated automatic gain control (AGC). The CLC5903 is a key component in the Enhanced Diversity Receiver Chipset (EDRCS) which includes one CLC5903 Dual Digital Tuner / AGC, two CLC5957 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. The CLC5903 is an enhanced replacement for the CLC5902 in the Diversity Receiver Chipset (DRCS).
