CLC5902 Dual Digital Tuner/AGC

The CLC5902 block diagram is shown in Figure 2. The CLC5902 contains two identical digital down-conversion (DDC) circuits. Each DDC accepts a 14-bit sample at up to 52MSPS, down converts from a selected carrier frequency to baseband, decimates the signal rate by a programmable factor ranging from 3.

May 1999 CLC5902 Dual Digital Tuner/AGC N CLC5902 Dual Digital Tuner/AGC 0 0 General Overview 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).
