The QTH-NKS-12 is an 8-channel 14-bit serial ADC at 125MSPS and dual-channel 14-bit DAC at 200MSPS that enable simultaneous and high speed sensitivity. This module was designed based on four-channel ADS6445 ADC of TI company with serial LVDS outputs and dual-channel DAC5672 DAC of TI company with CMOS parallel 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.
