The DAC39RF12 and ’RFS12 are a family of dual and single channel digital-to-analog converters (DAC) with 16-bit resolution. 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 24GSPS for a single channel or 12 GSPS for two channels. The devices can generate signals of up to 12, 7.5, and 6GHz signal bandwidth (8, 12, and 16-bit input resolution) at carrier frequencies exceeding 10GHz enabling direct sampling through C-band and into X-band.

The high sampling rate, output frequency range, 64-bit NCO frequency resolution and any frequency hopping with phase coherence also makes the device 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.
