Product Description

FH9680 is an FMC card compliant with the VITA57.1 standard, featuring a JESD204B (Subclass 1) interface. This subcard provides 4 channels of 14-bit ADC acquisition with selectable sampling rates up to 1.25 GSPS. The ADC device utilizes the AD9680 chip from Analog Devices Inc. (ADI), with a full-power -3dB analog input bandwidth of up to 2 GHz. The interface between the ADC and the FPGA host is established via a JESD204B interface with configurable lane configuration..

This board is mainly designed for applications such as communication and wireless infrastructure, radar, broadband communication, millimeter wave communication, and automatic testing equipment
