Highly integrated AD9154 quad, 16-bit D/A
converter delivers 2.4-GSPS bandwidth, enabling superior
performance and multi-carrier generation to the Nyquist frequency
in baseband mode.
Analog Devices, Inc. (NASDAQ: ADI), a global leader in
high-performance semiconductors for signal processing applications,
today introduced a quad-channel, 2.4-GSPS, 16-bit D/A converter
with industry leading dynamic range performance in the 100- to
300-MHz band for complex IF transmitters. The highly integrated
AD9154 quad, 16-bit D/A converter is the only device of its kind to
include an on-chip PLL (phase-locked loop) and eight-lane JESD204B
interface. The combination of features allows designers to use a
single device to meet all of their requirements in multicarrier GSM
and LTE transmitters designed for wireless macro base stations,
point-to-point microwave radio, military radios and radio test
equipment. The new converter includes a range of features optimized
for complex IF (intermediate frequency) transmit applications,
including complex digital modulation, input-signal power detection,
and gain, phase and offset compensation. Watch a video on the new

The AD9154 quad, 2.4-GSPS, 16-bit D/A converter is designed to
up-convert a pair of I/Q digital input signals, creating a complex
IF signal at the input to a pair of on-chip D/A converter cores.
The new device features several interpolation modes, increasing the
sampling rate of the digital signal to the Nyquist frequency to
enable simpler, less costly transmitter filters following the D/A
converter analog output. The AD9154 additionally includes
digital-signal correction for quadrature modulator up-converters to
cancel RF (radio frequency) local oscillator feed-through and
unwanted side-bands.
The AD9154 converter was designed with an eight-lane JESD204B
interface that simplifies board layout by providing deterministic
latency and multi-device synchronization for radio transmitters
that use multiple antennas—an increasingly common feature in
wireless base stations, radar and military radio
communications.
The AD9154 quad, 16-bit D/A converters extends ADI’s transmit
capabilities to the 100- to 300-MHz range, and joins the AD9144
quad, 16-bit D/A converter, which operates in the DC to 100-MHz
range, and will be joined later in 2015 by a 16-bit dual-channel
D/A converter.
AD9154 Key Features:
- Single-carrier LTE 20-MHz bandwidth
ACLR = 76.7 dBC at 180-MHz IF
- Six-carrier GSM IMD = 78-dBC, 600-kHz
carrier spacing at 180-MHz IF
- SFDR = 72-dBC at 180-MHz IF, -6
dBFS
- 8-lane JESD204B interface
- Support for quad-DAC or dual-DAC
mode
- Low power: 2.1-W at 1.5 GSPS
