The FMC-NKS-401110 is a 4-channel 16-bit ADC at 125MSPS synchronous and maximum sampling rate and single channel 18-bit DUC at 1GSPS synchronous and maximum sampling rate. This module was designed based on dual-channel AD9268 ADC of Analog Device company with DDR LVDS or CMOS outputs and single-channel AD9957 DUC of Analog Device company with CMOS inputs. Because of containing a FMC-HPC connector, FMC-NKS-401110 is mechanically and electrically compliant to VITA 57.1 standard. Controlling of clock source, sampling frequency and calibration by a SPI BUS are its other features. The clock sampling can be provided from an external or internal source and then send to distribution clock unit. Additionally, a trigger input for customized sampling control is available. This module can use on every carrier card which follows the VITA 57.1 standard; therefore it can have the maximum data throughput and minimum latency.
