CLC5903 双路数字调谐器/AGC

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). The main improvements relative to the CLC5902 are a 50% increase in maximum sample rate from 52MHz to 78MHz, a 62% reduction in power consumption from 760mW to 290mW, and the added flexibility to independently program filter coefficients in the two channels.
