GENERAL DESCRIPTION

The AD9625 is a 12-bit monolithic sampling analog-to-digital

converter (ADC) that operates at conversion rates of up to

2.0 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 jamming/antijamming measures.

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.

PRODUCT HIGHLIGHTS

1. High performance: exceptional SFDR in high sample rate

applications, direct RF sampling, and on-chip reference.

2. Flexible digital data output formats based on the JESD204B

specification.

3. Control path SPI interface port that supports various

product features and functions, such as data formatting,

gain, and offset calibration values.
