GENERAL DESCRIPTION

The AD9753 is a dual, muxed port, ultrahigh speed, single-
channel, 12-bit CMOS DAC. It integrates a high quality 12-bit
TxDAC+ core, a voltage reference, and digital interface circuitry
into a small 48-lead LQFP package. The AD9753 offers excep-
tional ac and dc performance while supporting update rates up
to 300 MSPS.
The AD9753 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.
The DAC utilizes a segmented current source architecture
combined with a proprietary switching technique to reduce
glitch energy and to maximize dynamic accuracy. Differential
current outputs support single-ended or differential applica-
tions. The differential outputs each provide a nominal full-scale
current from 2 mA to 20 mA.
The AD9753 is manufactured on an advanced low cost 0.35 µm
CMOS process. It operates from a single supply of 3.0 V to 3.6 V
and consumes 155 mW of power.
PRODUCT HIGHLIGHTS
The AD9753 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 12-Bit Latched, Multiplexed Input Ports. The AD9753
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 AD9753 includes a 1.20 V
temperature-compensated band gap voltage reference.

CAUTION
ESD (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
AD9753 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.
