GENERAL DESCRIPTION

The AD9139 is an 16-bit, high dynamic range digital-to-analog converter (DAC) that provides a sample rate of 1600 MSPS, permitting a multicarrier generation up to the Nyquist frequency.

FEATURES

Selectable 1× or 2× interpolation filter

Support input signal bandwidth up to 575 MHz

Very small inherent latency variation: <2 DAC clock cycles

Proprietary low spurious and distortion design

6-carrier GSM ACLR = 79 dBc at 200 MHz IF

SFDR >85 dBc (bandwidth = 300 MHz) at zero IF

Flexible 16-bit LVDS interface

Supports word and byte load

Multiple chip synchronization

Fixed latency and data generator latency compensation

FIFO eases system timing and includes error detection

High performance, low noise PLL clock multiplier

Digital inverse sinc filter

Low power: 700 mW at 1230 MSPS

72-lead LFCSP
