The DAC39RF20 is a single and dual channel digital-to-analog converter (DAC) with 16-bit resolution. With an external full rate clock, the devices support 22GSPS with single edge sampling modes (NRZ and RF) and 44GSPS in dual edge sampling modes (DES2XL, DES2XH). When using the internal PLL/VCO, the devices support 17GSPS with single edge sampling modes (NRZ and RF) and 34GSPS in dual edge sampling modes (DES2XL, DES2XH). The devices can be used as noninterpolating or interpolating DACs for either direct RF sampling or complex baseband signal generation. The maximum input data rate for two channels is 21GSPS (12-bit resolution) or 15.75GSPS (16-bit resolution). The maximum rate for one channel is 22GSPS (16-bit resolution). The device can generate signals greater than 10GHz bandwidth at frequencies exceeding 20GHz, enabling direct sampling through Ku band.
