The AD6659 is a dual-channel IF receiver with a 12-bit, 80 MSPS output data rate per channel. It operates on a 1.8V analog supply and integrates features such as noise shaping requantizer (NSR) and quadrature error correction (QEC). It offers high signal-to-noise ratio, low power consumption, and is suitable for a variety of applications.
The AD6659 is a mixed‑signal, dual‑channel IF receiver that integrates two 12‑bit ADCs, a noise‑shaping requantizer (NSR) and quadrature error correction (QEC). It operates from a single 1.8 V analog supply with a separate 1.8 V‑3.3 V digital output driver supply and supports SPI‑controlled features such as programmable clock division, power‑down modes and digital test pattern generation.
The device is offered in a 64‑lead RoHS‑compliant LFCSP package, rated for –40 °C to +85 °C operation. Detailed specifications cover DC, AC, digital and switching parameters, along with pin configuration, timing diagrams and design guidelines for PCB layout and power management.
