The AD9121 is a dual, 14-bit, high dynamic range digital-to-analog converter (DAC) that provides a sample rate of 1230 MSPS, permitting multicarrier generation up to the Nyquist frequency.
The AD9121 TxDAC+® includes features optimized for direct conversion transmit applications, including complex digital modulation, and gain and offset compensation. The DAC outputs are optimized to interface seamlessly with analog quadrature modulators, such as the ADL537x F-MOD series from Analog Devices, Inc. A 4-wire serial port interface provides for programming/readback of many internal parameters. Full-scale output current can be programmed over a range of 8.7 mA to 31.7 mA. The AD9121 comes in a 72-lead LFCSP.
PRODUCT HIGHLIGHTS
- Ultralow noise and intermodulation distortion (IMD) enable high quality synthesis of wideband signals from baseband to high intermediate frequencies (IF).
- Proprietary DAC output switching technique enhances dynamic performance.
- Current outputs are easily configured for various single-ended or differential circuit topologies.
- Flexible LVDS digital interface allows the standard 28-wire bus to be reduced to one-half of the width.
APPLICATIONS
- Wireless infrastructure
- W-CDMA, CDMA2000, TD-SCDMA, WiMAX, GSM, LTE
- Digital high or low IF synthesis
- Transmit diversity
- Wideband communications: LMDS/MMDS, point-to-point

EVAL-AD9121
AD9121 Evaluation Board
Product Detail
This page contains evaluation board documentation and ordering information for evaluating the AD9121.
The AD9121 evaluation board, AD9121-M5375-EBZ, has the ADL5375 modulator on-board. To operate the evaluation boards, the user must apply power, a clock source, a digital data source, and be able to observe the DAC output on either a spectrum analyzer or an oscilloscope. The evaluation board comes with software which are ACE (Analysis | Control | Evaluation) and DPG Downloader Lite software that allows the user to program the SPI port. Via the SPI port, the DUT and clock circuitry can be programmed into any of its various operating modes.

Product Detail
The SDP-H1 is a high speed controller board for the System Demonstration Platform (SDP). The SDP-H1 has a Xilinx® Spartan 6 and an ADSP-BF527 processor with connectivity to the PC through a USB 2.0 high speed port. Controller boards allow for the configuration and capture of data on daughter boards from the PC via USB.
The SDP-H1 has a FMC low pin count ( LPC) connector with full differential LVDS and singled ended LVCMOS support. It also has the 120 pin connector, found on the SDP-B which exposes the Blackfin processors peripherals. This connector provides a configurable Serial, Parallel I2C and SPI and GPIO communications lines to the attached daughter board. The PC side software application for controlling the attached daughter board is provided with each of the daughter product evaluation boards or Circuits from the Lab reference Circuits.
The System Demonstration Platform is a collection of controller boards, interposer boards, and daughter boards, used for easy, low cost evaluation of ADI components and reference circuits. For a general overview of the entire platform visit the System Demonstration Platform homepage www.analog.com/sdp
See the full list of compatible Product Evaluation Boards and Circuits from the Lab Reference Circuit Boards that require the SDP-B. All SDP-S compatible daughter boards can be used with the SDP-B.
