TI simplifies complex signal generation with wide bandwidth digital-to-analog converter and amplifier development tool

Kit extends TI's world-class support for high-speed analog designs

DALLAS, Sept. 8 /PRNewswire/ -- Texas Instruments Incorporated (TI) (NYSE: TXN) introduced today a leading-edge support tool that enables designers to rapidly evaluate signal chain performance for test and measurement, industrial and communications applications, including arbitrary waveform and signal generators. The development kit simplifies the complexity of interfacing between high-speed digital-to-analog converters (DAC) and amplifiers and includes clocking and power management devices to further ease design and reduce cycle time. In addition, the tool provides customers with the flexibility to implement alternative design configurations based on the unique requirements of the system, all configurable via an easy-to-use graphical user interface (GUI). (For more information, see http://www.ti.com/tsw3070-pr)

The TSW3070 development kit includes a high-speed DAC, two amplifiers, a complete on-board clocking solution and power supply circuitry, including the following:

    --  DAC5682Z dual-channel, 1-GSPS DAC with current sink output
    --  OPA695 current feedback amplifier with 1.4-GHz bandwidth
    --  THS3091/5 high voltage swing amplifier with 30-V supply voltage
    --  CDCM7005 jitter cleaner with 800-MHz VCXO and 10-MHz reference
    --  TPS7675x, TPS5430, UCC284-5 on board voltage supply solution from a
        single 6-V wall supply

In addition, the kit also features a user-friendly GUI for easy DAC configuration.

The TSW3070 provides designers with the flexibility to implement multiple configuration options. The DAC5682Z converter with LVDS interface offers many digital features which can be configured using the GUI such as:

    --  Selectable low-, high-, or bypass filter modes
    --  Interpolation: 2x, 4x or bypass
    --  Optional +/-Fs/4 or +/-Fs/8 coarse mixer
    --  8 sample input data FIFO

Designers can drive the DAC output to either the OPA695 or the THS3091/5, enabling customers to evaluate a high-frequency signal to support wide bandwidth or a large signal swing. The amplifiers also simplify the signal chain requirement for level-shifting, gain and differential to single-ended conversion while taking into consideration the DAC compliance voltage and output current specification. As an additional option, designers can bypass the amplifiers and send the signal to a passive transformer output without gain.

TI offers a host of other market-leading solutions-based tools to address customer design challenges, reduce prototyping costs and speed development time. For instance, customers can utilize the LVDS outputs from TI's TSW3100 digital pattern generator to drive the LVDS bus into the TSW3070's DAC5682Z input interface with up to 256 mega vector pattern depths.
