ANALOG DEVICES AD6688-3000EBZ Evaluation Board, AD6688, 1.2GHz RF-Sampling Receiver

AD6688-3000EBZ is an evaluation board that supports the AD6688-3000, a 14bit, 3GSPS dual analogue-to-digital converter (ADC). The device has an on-chip buffer and a sample-and-hold circuit designed for low power, small size, and ease of use. This device is designed support direct RF sampling analogue signals of up to 5GHz. The 3dB bandwidth of the ADC input is greater than 9GHz. The AD6688 is optimized for wide input bandwidth, high sampling rate, excellent linearity, and low power in a small package. This reference design provides all of the support circuitry required to operate the ADC in its various modes and configurations. It is designed to interface directly with the ADS7-V2EBZ data capture card, allowing users to download captured data for analysis. The device control and subsequent data analyses can now be done using the ACE software package.
