Analog Converter

Data Sheet

AD9139

FEATURES

GENERAL DESCRIPTION

Selectable 1× or 2× interpolation filter

Support input signal bandwidth up to 575 MHz

The AD9139 is an 16-bit, high dynamic range digital-to-analog

converter (DAC) that provides a sample rate of 1600 MSPS,

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

permitting a multicarrier generation up to the Nyquist frequency.

The AD9139 TxDAC+® includes features optimized for wideband

communication applications, including 1× and 2× interpolation, a

delay locked loop (DLL) powered high speed interface, sample

error detection, and parity detection. A 3-wire serial port

interface provides for the programming/readback of many

internal parameters. A 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.

PRODUCT HIGHLIGHTS

1. 575 MHz achievable input signal bandwidth.

2. Advanced low spurious and distortion design techniques

provide high quality synthesis of wideband signals from

baseband to high intermediate frequencies.

3. Very small inherent latency variation simplifies both software

and hardware design in the system. It allows easy multichip

synchronization for most applications.

Low power: 700 mW at 1230 MSPS

72-lead LFCSP

APPLICATIONS

Wireless communications: 3G/4G and MC-GSM base stations,

wideband repeaters, software defined radios

Wideband communications: point-to-point, LMDS/MMDS

Transmit diversity/MIMO

4. Low power architecture improves power efficiency.
