The AD9785/AD9787/AD9788 are 12-bit, 14-bit, and 16-bit, high dynamic range TxDAC® devices, respectively, that provide a sample rate of 800 MSPS, permitting multicarrier generation up to the Nyquist frequency. Features are included for optimizing direct conversion transmit applications, including complex digital modulation, as well as gain, phase, and offset compensation. The DAC outputs are optimized to interface seamlessly with analog quadrature modulators, such as the ADL5375 family from Analog Devices, Inc. A serial peripheral interface (SPI) provides for programming and readback of many internal parameters. Full-scale output current can be programmed over a range of 10 mA to 30 mA. The AD9785/AD9787/AD9788 family is manufactured on a 0.18 μm CMOS process and operates from 1.8 V and 3.3 V supplies. It is enclosed in a 100-lead TQFP package.

Product Highlights

  1. Low noise and intermodulation distortion (IMD) enable high quality synthesis of wideband signals from baseband to high intermediate frequencies.
  2. Proprietary DAC output switching technique enhances dynamic performance.
  3. CMOS data input interface with adjustable setup and hold.
  4. Low power complex 32-bit numerically controlled oscillators (NCOs).

Applications

  • Wireless infrastructure
    W-CDMA, CDMA2000, TD-SCDMA, WiMAX, GSM
  • Digital high or low IF synthesis
  • Transmit diversity
  • Wideband communications
    LMDS/MMDS, point-to-point

SDP-H1

High Speed Controller Board

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

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.
