Texas Instruments DAC39RF10 & DAC39RFS10 DACs

Texas Instruments DAC39RF10 and DAC39RFS10 Digital-to-Analog Converters (DACs) offer dual and single channel options with 16-bit resolution. The DAC39RF10 and DAC39RFS10 adjust for noninterpolation or interpolation for direct RF sampling or complex baseband signal generation. The devices provide a 20.48GSPS maximum input data rate for a single channel or 10.24GSPS for two channels.

The TI DAC39RF10 and DAC39RFS10 DACs can generate signals of up to 10GHz, 7.5GHz, and 5GHz signal bandwidth (8, 12, and 16-bit input resolution) at carrier frequencies exceeding 8GHz 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 make the devices 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 SYSREF.
