The AD9142A is a dual, 16-bit, high dynamic range digital-to-analog converter (DAC) that provides a sample rate of 1600 MSPS, permitting a multicarrier generation up to the Nyquist frequency. The AD9142A TxDAC+® includes features optimized for direct conversion transmit applications, including complex digital modulation, input signal power detection, and gain, phase, and offset compensation. The DAC outputs are optimized to interface seamlessly with analog quadrature modulators, such as the ADL537x F-MOD series and the ADRF670x series from Analog Devices, Inc. A 3-wire serial port interface provides for the programming/readback of many internal parameters. Full-scale output current can be programmed over a range of 9 mA to 33 mA. The AD9142A is available in a 72-lead LFCSP.
PRODUCT HIGHLIGHTS
- Wide signal bandwidth (BW) enables emerging wideband and multiband wireless applications.
- Advanced low spurious and distortion design techniques provide high quality synthesis of wideband signals from baseband to high intermediate frequencies.
- Very small inherent latency variation simplifies both software and hardware design in the system. It allows easy multichip synchronization for most applications.
- New low power architecture improves power efficiency (mW/MHz/channel) by 30%.
- Input signal power and FIFO error detection simplify designs for downstream analog circuitry protection.
- Programmable transmit enable function allows easy design balance between power consumption and wakeup time.
APPLICATIONS
- Wireless communications: 3G/4G and MC-GSM base stations,
wideband repeaters, software defined radios - Wideband communications: point-to-point, LMDS/MMDS
- Transmit diversity/MIMO
- Instrumentation
- Automated test equipment

SDP-H1
High Speed Controller Board
Features and Benefits
- Xilinx® Spartan 6
- 1 x FMC Low Pin Count ( LPC) connector
- LVDS and single ended LVCMOS signaling
- DDR2
- JTAG header
- Blackfin processor ADSP-BF527
- 1 x small Footprint 120 pin connector
- Configurable Peripheral Interfaces SPI, SPORT, I2C, GPIO, Asynchronous Parallel, PPI, Timers
- USB 2.0 interface to the PC
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.

EVAL-AD9142A
AD9142A Evaluation Board
Product Detail
The AD9142A evaluation board, AD9142A-M5372-EBZ, has the ADL5372 modulator on board and the AD9142A-M5375-EBZ has the ADL5375 modulator on-board. The evaluation boards connects to a controller board for quick evaluation of AD9142A. 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. A clock distribution chip AD9516 is included on this EVB as a clock fan-out and frequency divider for the DACCLK, REFCLK and ADS7-V2EBZ or SDP-H1 input clock. 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.
