APPLICATIONS Spectrum analyzers Military communications Radar High performance digital storage oscilloscopes Active jamming/antijamming Electronic surveillance and countermeasures GENERAL DESCRIPTION PRODUCT HIGHLIGHTS The AD9625 is a 12-bit monolithic sampling analog-to-digital converter (ADC) that operates at conversion rates of up to 2.6 giga samples per second (GSPS). This product is designed for sampling wide bandwidth analog signals up to the second Nyquist zone. The combination of wide input bandwidth, high sampling rate, and excellent linearity of the AD9625 is ideally suited for spectrum analyzers, data acquisition systems, and a wide assortment of military electronics applications, such as radar and electronic countermeasures. 1. 2. 3. High performance: exceptional SFDR in high sample rate applications, direct RF sampling, and on-chip reference. Flexible digital data output formats based on the JESD204B specification. Control path SPI interface port that supports various product features and functions, such as data formatting, gain, and offset calibration values. The analog input, clock, and SYSREF± signals are differential inputs. The JESD204B-based high speed serialized output is configurable in a variety of one-, two-, four-, six-, or eight-lane configurations. The product is specified over the industrial temperature range of −40°C to +85°C, measured at the case. Rev.
