Description

DDS39RF10 and ’RFS10 are a family of dual and single channel direct digital synthesizers with 16-bit resolution digital-to-analog converters (DAC). The high sampling rate, output frequency range, 64-bit NCO frequency resolution and any frequency hopping with phase coherence makes the device capable of arbitrary waveform generation (AWG) and direct digital synthesis (DDS).

The devices can also be used as interpolating DACs for narrowband direct RF sampling or complex baseband signal generation. The maximum input data rate is 775MSPS for a single channel or 388MSPS for two channels. The devices can generate signals of up to 620MHz signal bandwidth (16-bit input resolution) at carrier frequencies exceeding 10GHz enabling direct sampling through C-band and into X-band.

A JESD204B and JESD204C compatible serial interface has 2 receiver pairs capable of up to 12.8Gbps each. The interface is JESD204B and JESD204C subclass-1 compliant for deterministic latency and multi-device synchronization through the use of SYSREF.
