Wideband converter in ultra-small package maximizes carrier placement flexibility

DALLAS, March 31 /PRNewswire/ -- Texas Instruments Incorporated (TI) (NYSE: TXN - News) today introduced a high-performance 16-bit, dual channel, 1 GSPS (giga sample per second) digital-to-analog converter (DAC) family. The new single and dual-channel DAC family features a low-voltage differential signaling (LVDS) data input port at 1 Gbps, providing up to 400 MHz signal bandwidth. In addition, the DAC family offers flexible configuration options as well as industry-leading tools and support to ease design and speed time to market for base stations, wideband IF transmitters, radar, and test and measurement equipment.

Best-in-class performance and flexibility in a space-saving package

Offered in a small 9 mm x 9 mm QFN package, the DAC568x family builds upon TI's commitment to offer high-performance, integrated solutions by providing a 70 percent space savings over traditional data converters. The devices provide several configuration options to support different transmit architectures, such as direct up-conversion, real or complex IF, and different wireless air interfaces such as WCDMA, TD-SCDMA, WiMAX and LTE. For an output frequency of 160 Mhz, the devices achieve 73 dB ACPR for a single-carrier WCDMA application or 67 dBc for a four-carrier application. Along with the single-channel DAC5681 and DAC5681Z, the dual DAC5682Z offers many digitally configurable features such as:

-- Selectable low-, high-, or bypass filter modes
-- Interpolation: 2x, 4x or bypass
-- Optional +/-Fs/4 or +/-Fs/8 coarse mixer
-- Optional 2x-32x clock multiplying PLL
-- 8 sample input data FIFO
