The CLC5903SM from Texas Instruments is a Dual Digital Tuner / AGC IC, functioning as a key component in digital downconverter systems. It supports a maximum sample rate of 78MSPS and features two independent channels with 14-bit inputs. The device incorporates a series of filters, including a 4-stage CIC filter and two symmetric FIR filters (21-tap and 63-tap), allowing for programmable decimation ratios and precise channel filtering.
This IC offers high dynamic range digital tuning and filtering, with independent control over tuning, phase offset, filter coefficients, and gain settings for each channel. The integrated AGC controller monitors ADC output and adjusts DVGA settings to maintain optimal signal levels. The CLC5903SM is designed for surface mount applications and comes in a 128-LFBGA package.
With features like greater than 100 dB image rejection and spurious free dynamic range, and a tuning resolution of 0.02 Hz, the CLC5903SM is suitable for demanding RF receiver applications. Its low power consumption, at 145mW/channel at 52 MHz, makes it an efficient choice for various communication systems.
