3 Description
The DAC39RF10EF and 'RFS10EF 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 20.48
GSPS for a single channel or 10.24 GSPS for two
channels. The device can generate signals of up to
10, 2.73 or 1 GHz signal bandwidth (8, 11, 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
DAC39RF10EF and 'RFS10EF 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.
