AD9139 16-Bit, 1600 MSPS, TxDAC+ Digital-to-Analog Converter
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.
APPLICATIONS
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.
