The devices can be used as non-interpolating or interpolating DACs for either direct RF sampling or complex baseband signal generation. The maximum input data rate is 20.8GSPS for a single channel or 10.4 GSPS for two channels. The devices can generate signals of up to 10, 7.5, and 5GHz signal bandwidth (8, 12, and 16- bit input resolution) at carrier frequencies exceeding 10GHz enabling direct sampling in X-band. The high sampling rate, output frequency range, 64- bit NCO frequency resolution and any frequency hopping with phase coherence also makes the DAC39RF10-Sx and 'RFS10-Sx capable of arbitrary waveform generation (AWG) and direct digital synthesis (DDS). A JESD204B and JESD204C compatible serial interface has 16 receiver pairs capable of up to 12.8Gbps. The interface is JESD204B and JESD204C subclass-1 compliant for deterministic latency and multi-device synchronization through the use of SYSREF.
