Overview
The AD6657BBCZRL, produced by Analog Devices Inc., is an 11-bit, 200 MSPS (mega-samples per second) quad-channel intermediate frequency (IF) receiver. This device is specifically designed to support multi-antenna systems in telecommunications applications, where high dynamic range performance, low power consumption, and a compact size are essential.
The AD6657 features integrated noise shaping requantizer (NSR) circuitry, which enhances the signal-to-noise ratio (SNR) within a limited portion of the Nyquist bandwidth. It also includes a duty cycle stabilizer (DCS) to compensate for variations in the ADC clock duty cycle, ensuring excellent performance across various operating conditions.
