Product Description
FH9681 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 a fixed sampling rate of 1 GSPS. The ADC device utilizes the GMS011 chip from CETC24, which is fully compatible with the AD9680-1000 from Analog Devices Inc. (ADI), offering a full-power -3 dB analog input bandwidth of up to 2 GHz. The interface between the ADC and the FPGA host is established via 8 high-speed serial GTX transceivers. The board features DC coupling, supporting analog signal input from DC to 2 GHz with an amplitude range of 2 Vpp
This board is mainly designed for applications such as communication and wireless infrastructure, radar, broadband communication, millimeter wave communication, and automatic testing equipment
Applications
● Radar and smart antennas, wireless infrastructure
● Broadband RF signal processing, signal generator
