IF Analog-to-Digital Converter with Digital Downconverter
Features
12-BIT, 80MSPS ADC INTEGRATED DIGITAL DOWNCONVERTER (DDC):
DESCRIPTION
The AFE8201 consists of a general-purpose, 80MSPS, 12-bit analog-to-digital converter (ADC), a digital downconverter (DDC), and user-programmable digital filters. It is designed to sample narrowband (2.5MHz or less) IF signals and digitally mix, filter, and decimate the signals to baseband. The DDC consists of a digital quadrature mixer followed by a CIC decimation filter and FIR filters. The mixer frequency and initial phase are independently programmed by 32-bit control words.
