Analog Devices Intros Dual, 16-Bit, 1.25-GSPS,
Digital-to-Analog Converter IC Incorporates a JESD204 Serial
Input
|
June 18, 2012 Press Release
-- Simplify the FPGA Interface
IMS2012 International Microwave Symposium
MONTREAL--( BUSINESS
WIRE)-- 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.
