The AD9125 is a dual, 16-bit, high dynamic range TxDAC+® digital-to-analog converter (DAC) that provides a sample rate of 1000 MSPS, permitting a multicarrier generation up to the Nyquist frequency. It 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 allows 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 AD9125 comes in a 72-lead LFCSP.

PRODUCT HIGHLIGHTS

  1. Ultralow noise and intermodulation distortion (IMD) enable high quality synthesis of wideband signals from baseband to high intermediate frequencies.
  2. A proprietary DAC output switching technique enhances dynamic performance.
  3. The current outputs are easily configured for various single-ended or differential circuit topologies.
  4. Flexible CMOS digital interface allows the standard 32-wire bus to be reduced to a 16-wire bus.

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
  • Cable modem termination systems

EVAL-AD9125

AD9125 Evaluation Board

AD9125 Evaluation Board

Features and Benefits

  • Full featured evaluation board for the AD9125
  • Includes options to evaluate:
    • DAC only (Two DAC output)
    • DAC and ADL537X quadrature modulator
  • USB interface for configuration
  • Internal or external power supply regulation
  • Data pattern generator and SPI software interfaces

Product Detail

The AD9125 evaluation board comes in two models; the AD9125-M5372-EBZ has the ADL5372 modulator on board, and the AD9125-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. A low jitter sine or square wave clock will work well as a source. The evaluation board comes with software which 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.

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.
