PRODUCT DESCRIPTIONThe AD9751 is a dual muxed port, ultrahigh speed, single-
channel, 10-bit CMOS DAC. It integrates a high quality 10-bit
TxDAC+ core, a voltage reference, and digital interface circuitry
into a small 48-lead LQFP package. The AD9751 offers excep-
tional ac and dc performance while supporting update rates up
to 300MSPS.
The AD9751 has been optimized for ultrahigh speed applica-
tions up to 300 MSPS where data rates exceed those possible on
a single data interface port DAC. The digital interface consists
of two buffered latches as well as control logic. These latches
can be time multiplexed to the high speed DAC in several ways.
This PLL drives the DAC latch at twice the speed of the exter-
nally applied clock and is able to interleave the data from the
two input channels. The resulting output data rate is twice that
of the two input channels. With the PLL disabled, an external
2× clock may be supplied and divided by two internally.
The CLK inputs (CLK+/CLK–) can be driven either differen-
tially or single-ended, with a signal swing as low as 1 V p-p.

Base Stations
Digital Synthesis
QAM and OFDMThe DAC utilizes a segmented current source architecture com-
bined with a proprietary switching technique to reduce glitch
energy and maximize dynamic accuracy. Differential current
outputs support single-ended or differential applications. The
differential outputs each provide a nominal full-scale current
from 2mA to 20 mA.
The AD9751 is manufactured on an advanced low cost 0.35µm
CMOS process. It operates from a single supply of 3.0 V to 3.6V
and consumes 155 mW of power.
PRODUCT HIGHLIGHTSThe AD9751 is a member of a pin compatible family of high
speed TxDAC+s, providing 10-, 12-, and 14-bit resolution.Ultrahigh Speed 300 MSPS Conversion Rate.Dual 10-Bit Latched, Multiplexed Input Ports. The AD9751
features a flexible digital interface allowing high speed data
conversion through either a single or dual port input.Low Power. Complete CMOS DAC function operates on
155 mW from a 3.0 V to 3.6 V single supply. The DAC full-
scale current can be reduced for lower power operation.On-Chip Voltage Reference. The AD9751 includes a 1.20V
temperature compensated band gap voltage reference.

CAUTIONESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD9751 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
