The QTH-NKS-01 is a dual-channel 16-bit DAC at 160MSPS (no interpolation) synchronous and maximum sampling rate of 400MSPS (8x interpolation). This module was designed based on dual-channel AD9777 DAC of Analog Device company with LVCMOS 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.
