GENERAL DESCRIPTION

The AD9739 is a 14-bit, 2.5 GSPS high performance RF digital-

to-analog converter (DAC) capable of synthesizing wideband

signals from dc up to 3.0 GHz. Its DAC core features a quad-

switch architecture that provides exceptionally low distortion

performance with an industry-leading direct RF synthesis

capability. This feature enables multicarrier generation up to

the Nyquist frequency in baseband mode as well as second and

third Nyquist zones in mix mode. The output current can be

programmed over the 8.66 mA to 31.66 mA range.

PRODUCT HIGHLIGHTS

1. Ability to synthesize high quality wideband signals with

bandwidths of up to 1.25 GHz in the first or second

Nyquist zone.

2. A proprietary quad-switch DAC architecture provides

exceptional ac linearity performance while enabling mix

mode operation.

3. A dual-port, double data rate, LVDS interface supports the

maximum conversion rate of 2500 MSPS.

4. On-chip controllers manage external and internal clock

domain skews.

5. A multichip synchronization capability.

6. Programmable differential current output with a 8.66 mA

to 31.66 mA range.

The inclusion of on-chip controllers simplifies system integration.

A dual-port, source synchronous, LVDS interface simplifies the

digital interface with existing FGPA/ASIC technology. On-chip

controllers are used to manage external and internal clock domain

variations over temperature to ensure reliable data transfer from

the host to the DAC core. Multichip synchronization is possible

with an on-chip synchronization controller. A serial peripheral

interface (SPI) is used for device configuration as well as readback

of status registers.

The AD9739 is manufactured on a 0.18 μm CMOS process and

operates from 1.8 V and 3.3 V supplies. It is supplied in a 160-ball

chip scale ball grid array for reduced package parasitics.
