DAC5670-SP 14 位 2.4GSPS 数模转换器
The DAC5670 is a 14-bit 2.4-GSPS digital-to-analog converter (DAC) with dual demultiplexed differential input ports. The DAC5670 is clocked at the DAC sample rate and the two input ports run at a maximum of 1.2 GSPS. An additional reference bit input sequence is used to adjust the output clock delay to the data source, optimizing the internal data latching clock relative to this reference bit with a delay lock loop (DLL).
The DAC5670 also can accept data up to 1.2 GSPS on one input port the same clock configuration. In the single port mode, repeating the input sample (A_ONLY mode), 2 times interpolation by zero stuff (A_ONLY_ZS mode), or 2 times interpolation by repeating and inverting the input sample (A_ONLY_INV) are used to double the input sample rate up to 2
