7.1 Overview

The DAC39RF10 および RFS10 are a family of single and dual channel digital-to-analog converters (DAC) with 16-bit resolution. The device can be used as single channel or dual channel non-interpolation DACs. The device can also be used as interpolating DACs in either direct RF sampling mode or baseband mode, supporting up to four complex (IQ) input streams that can be combined at different RF frequencies. The maximum input data rate is 20.48 GSPS in single channel mode or 10.24 GSPS in dual channel mode or baseband mode. The device can generate signals of up to 10, 7.8, 5 GHz signal bandwidth (8, 12, 16-bit input resolution) at carrier frequencies exceeding 8 GHz enabling direct sampling through C-band and into X-band.

The 64-bit NCO frequency resolution and infinite frequency hopping with phase coherence, continuity and reset options makes the device ideally suited for arbitrary waveform generation (AWG) and direct digital synthesis (DDS).

A JESD204C compatible serial interface with 8b/10b and 64b/66b encoding options has 16 receiver pairs capable of up to 12.8 Gbps. The interface is JESD204C subclass-1 compliant for deterministic latency and multi-device synchronization through the use of SYSREF. The SYSREF Windowing feature allows for automatic SYSREF timing calibration.
