AD9265 - 16-bit, 125MSPS analog-to-digital converter (ADC)

The AD9265 is a 16-bit, 125MSPS analog-to-digital converter (ADC) featuring a wide bandwidth differential sample-and-hold analog input amplifier supporting a variety of user-selectable input ranges.

This reference design includes a data capture interface and the external DDR-DRAM interface for sample storage. It allows programming the device and monitoring it's internal status registers. The board also provides other options to drive the clock and analog inputs of the ADC.
