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.
