DESCRIPTION  
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 2.4 GSPS.  
The DAC5670 operates with a single 3-V to 3.6-V supply voltage. Power dissipation is 2 W at maximum  
operating conditions. The DAC5670 provides a nominal full-scale differential current-output of 20 mA, supporting  
both single-ended and differential applications. An on-chip 1.2-V temperature-compensated bandgap reference  
and control amplifier allows the user to adjust the full-scale output current from the nominal 20 mA to as low as 5  
mA or as high as 30 mA. The output current can be directly fed to the load with no additional external output  
buffer required. The device has been specifically designed for a differential transformer coupled output with a  
50-Ω doubly-terminated load.  
The DAC5670 is available in a 252-ball GDKJ package. The device is characterized for operation over the  
temperature range –40°C to 85°C .
