MONTREAL -- June 18, 2012

IMS2012-- Analog Devices, Inc. (ADI), the data converter market share leader*
and a data conversion and signal processing technology innovator for over 47
years, today introduced the AD9128, a performance-leading 16-bit, 1.25-GSPS
transmit D/A converter (DAC) with integrated complex digital modulation
functionality, and featuring a JESD204A-compatible serial input. The AD9128’s
high-speed serial interface greatly simplifies and improves the data
connection between the DAC and the FPGA in a typical system implementation.

High-performance FPGAs are increasingly being utilized as processors in many
data-centric wireless and wired communications, radar, avionics, and medical
imaging applications. FPGAs are gaining favor due to their inherent advantages
of easier system development, reduced time-to-market, higher processing speed,
and on-the-fly programmability. However for higher-resolution, 1-GSPS+ data
converter applications, data transfers in and out of an FPGA have
traditionally been a design bottleneck because of interface bit-rate
limitations, interconnect layout complexity, and parallel interface board
space requirements. JESD204 was specifically developed to remedy these
constraints by defining a robust high-speed serial interface that is scalable
and accommodates data rates in the multiple Gbps range. ADI is committed to
embracing this standard in its ultra-high-speed data-converter technology, and
FPGA manufacturers are actively integrating this protocol into their
high-performance platforms.

The JESD204A-compliant AD9128 offers high sampling rate and high dynamic
range, enabling multicarrier generation up to the Nyquist frequency, and
includes features such as an on-chip 32-bit NCO (numerically-controlled
oscillator), allowing flexible placement of the IF (intermediate frequency),
complex digital modulation, and gain and offset compensation. A 4-wire serial
port interface provides for programming and read-back of many of the device’s
internal parameters and functions. The AD9128 supports GSM, WCDMA, TD-SCDMA,
CDMA2000, WiMAX, and LTE wireless communications standards.

The AD9128 high-speed D/A converter’s analog outputs are optimized to
interface seamlessly with analog quadrature modulators, such as ADI’s ADL537x
F-MOD series, and the ADCLK914 clock/data buffer that drives the AD9128 D/A
converter with clock input jitter performance of 110 fs. Other complementary
parts include the ADRF6702 quadrature modulator and ADRF6602 Rx mixer.
