3 Description
The DAC39RF10 is a family of single and dual
channel digital-to-analog converter (DAC) with 16-bit
resolution. The devices 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. 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, 7.5, and 5 GHz signal bandwidth (8,
12, and 16-bit input resolution) at carrier frequencies
exceeding 8 GHz 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 DAC39RF10 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 12.8
Gbps. The interface is JESD204B and JESD204C
subclass-1 compliant for deterministic latency and
multi-device synchronization through the use of
SYSREF.
