The AD9743/AD9745/AD976/AD9747 are pin-compatible, high dynamic range, dual digital-to-analog converters (DACs) with 10-/12-/14-/16-bit resolutions and sample rates of up to 250 MSPS. The devices include specific features for direct conversion transmit applications, including gain and offset compensation, and they interface seamlessly with analog quadrature modulators, such as the ADL5370.
A proprietary, dynamic output architecture permits synthesis of analog outputs even above Nyquist by shifting energy away from the fundamental and into the image frequency.
A serial peripheral interface (SPI) port provides full programmability. In addition, some pin-programmable features are offered for those applications without a controller.
- Low noise and intermodulation distortion (IMD) enables high quality synthesis of wideband signals.
- Proprietary switching output for enhanced dynamic performance.
- Programmable current outputs and dual auxiliary DACs provide flexibility and system enhancements.
- Wireless infrastructure:
W-CDMA, CDMA2000, TD-SCDMA, WiMAX
- Wideband communications:
Radio Frequency (RF) signal generators, arbitrary waveform generators

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/sdpSee 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.
