The QTH‐NKS‐11 is a 4‐channel 14‐bit ADC at 250MSPS and 4‐channel 16‐bit DAC at 1GSPS that enable simultaneous and high speed sensitivity. This module was designed based on dual‐channel ADS62P49 ADC of TI Company with CMOS or DDR LVDS outputs and dual‐channel DAC5682 DAC of TI Company with DDR LVDS inputs. The clock sampling can be provided from an external or internal source and then send to distribution clock unit. This module can use on every carrier card which follows the QSH/QTH standard; therefore it can have the maximum data throughput and minimum latency.
