The encode clock supports either differential or single-ended
input and is PECL-compatible. The output format is user-
selectable for binary or two’s complement and provides an
overrange (OR) signal.
Fabricated on an advanced BiCMOS process, the AD9433 is
available in a thermally enhanced 52-lead plastic quad flatpack
specified over the industrial temperature range (–40°C to
+85°C) and is pin-compatible with the AD9432.
PRODUCT HIGHLIGHTS
The AD9433 is a 12-bit monolithic sampling analog-to-digital
converter with an on-chip track-and-hold circuit and is designed
for ease of use. The product operates up to 125 MSPS conver-
sion rate and is optimized for outstanding dynamic performance
in wideband and high IF carrier systems.
The ADC requires a 5 V analog power supply and a differential
encode clock for full performance operation. No external refer-
ence or driver components are required for many applications.
The digital outputs are TTL/CMOS compatible and a separate
output power supply pin supports interfacing with 3.3 V or
2.5 V logic.
A user-selectable, on-chip proprietary circuit optimizes spurious-
free dynamic range (SFDR) versus signal-to-noise-and-distortion
(SINAD) ratio performance for different input signal frequencies,
providing as much as 83 dBc SFDR performance over the dc
to 70 MHz band.
1.
IF Sampling
The AD9433 maintains outstanding ac performance up to
input frequencies of 350 MHz. Suitable for 3G Wideband
Cellular IF sampling receivers.
2. Pin-Compatibility
This ADC has the same footprint and pin layout as the
AD9432, 12-Bit 80/105 MSPS ADC.
3. SFDR Performance
A user-selectable on-chip circuit optimizes SFDR performance
as much at 85 dBc from dc to 70 MHz.
4. Sampling Rate
At 125 MSPS, this ADC is ideally suited for current wireless
and wired broadband applications such as LMDS/MMDS
and cable reverse path.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD9433 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.
