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.
