Overview
The AD6674BCPZ-1000, produced by Analog Devices Inc., is a high-performance, 385 MHz bandwidth mixed-signal intermediate frequency (IF) receiver. This device is designed to support communications applications requiring the sampling of wide bandwidth analog signals up to 2 GHz. It features two 14-bit analog-to-digital converters (ADCs) with sampling rates of 1.0 GSPS, 750 MSPS, or 500 MSPS, along with various digital signal processing blocks including four wideband digital downconverters (DDCs), a noise shaping requantizer (NSR), and variable dynamic range (VDR) monitoring. The AD6674 is optimized for wide input bandwidth, high sampling rate, excellent linearity, and low power consumption in a compact package.
