More information about this board:

What is the input impedance?  The recommended input impedance is 50ohm.

What is the bandwidth? The analog input bandwidth is 750MHz.

What is the input voltage range? The recommend power supply is 5V, and IO voltage is 3.3V.

This this board uses multiple PMOD connectors, can you tell me the distance between them (pin 1 to pin 1 distance)? I want to know if it will fit into Digilent Arty-7 boards.

The pin1 to pin1 distance is 880mil(22.352mm), it will fit into Digilent Arty-7 boards.

I want to know the distance between the PMOD plugs (will it fit in the Digilent Arty-7 board)?

Also what impedance is the input?  What bandwidth can I expect?

18.3.1 ADC9226 Module Introduction

ADC9226 module adopts AD9226 chip design of ADI Company. This chip is a monolithic, 12-bit, 65 MSPS analog-to-digital converter (ADC). It uses a single power supply and has an on-chip high-performance sample-and-hold amplifier and voltage reference. It uses a multistage differential pipelined architecture with a data rate of 65 MSPS and guarantees no missing codes over the full operating temperature range.

See Figure 18.1 for ADC9226 timing diagram.
