16-Bit, 1600 MSPS, TxDAC+ Digital-to-Analog Converter
The AD9139 is an 16-bit, high dynamic range digital-to-analog converter (DAC) that provides a maximum update rate of 1600 MSPS, permitting multicarrier generation up to the Nyquist frequency. The AD9139 TxDAC+® includes features optimized for wide band communications applications, including 1× and 2× interpolation, a DLL based high speed interface, sample error detection, and parity detection. A 3-wire serial port interface provides for the programming/readback of many internal parameters. Full-scale output current can be programmed over a range of 9 mA up to 33 mA. The AD9139 is available in a 72-lead LFCSP.
- 575 MHz achievable input signal bandwidth.
- Advanced low spurious and distortion design techniques
provide high quality synthesis of wideband signals from
baseband to high intermediate frequencies.
- Very small inherent latency variation simplifies both software
and hardware design in the system. It allows easy multichip
synchronization for most applications.
- Low power architecture improves power efficiency.
- Wireless communications: 3G/4G and MC-GSM base stations,
wideband repeaters, software defined radios
- Wideband communications: point-to-point, LMDS/MMDS
- Transmit diversity/MIMO
- Automated test equipment
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
The AD9139-DUAL-EBZ connects to a DPG3 for quick evaluation of the AD9139, a high-speed, signal processing Digital to Analog Converter. The DPG3 automatically formats the data and sends it to the AD9139-DUAL-EBZ, simplifying evaluation of the device. The Evaluation Board (EVB) runs from a +5V supply. A clock distribution chip AD9516 is included on this EVB as a clock fan-out and frequency divider for the DACCLK, REFCLK, Frame, and DPG3 input clock. Also included is a quadrature modulator ADL5375 for quick DAC+IQMOD evaluation. Since AD9139 is a single channel converter, dual AD9139s are used on the board to work as I and Q, which typically applies to the case of wideband applications. Figure 2 is an image of the top side of the AD9139-DUAL-EBZ.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
