The AD9146 is a dual, 16-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 AD9146 TxDAC+® includes features optimized for direct conversion transmit applications, including complex digital mod-ulation, 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 3-wire serial port interface provides for program-ming/readback of many internal parameters. Full-scale output current can be programmed over a range of 8.7 mA to 31.7 mA. The AD9146 comes in a 48-lead LFCSP.
- Ultralow noise and intermodulation distortion (IMD) enable high quality synthesis of wideband signals from baseband to high intermediate frequencies.
- A proprietary DAC output switching technique enhances dynamic performance.
- The current outputs are easily configured for various single-ended or differential circuit topologies.
- Compact LVDS digital interface offers reduced width data bus.
- 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

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.

The ADS7-V2 Evaluation Board was developed to support the evaluation of Analog Devices high speed A/D converters, D/A converters and Transceivers with JESD204B bit rates up to 13.1 Gbps. The Quick Start Wiki site listed below provides a high level overview of the platform. In addition, each use case of the board has its own section (e.g. Using the ADS7-V2 for High Speed A/D Converter Evaluation). The ADS7-V2 is intended to be used only with specified Analog Devices Evaluation Boards. The ADS7-V2 is not intended to be used as a development platform, and no support is available for standalone operation. Please refer to Xilinx and its approved distributors for FPGA Development Kits
