Dual, 16-Bit, 1600 MSPS, TxDAC+

Digital-to-Analog Converter

Data Sheet

AD9142

FEATURES

GENERAL DESCRIPTION

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 ZIF

Flexible 16-bit LVDS interface

Supports word and byte load

Multiple chip synchronization

Fixed latency and data generator latency compensation

Selectable 2×, 4×, 8× interpolation filter

Low power architecture

f_S/4 power saving coarse mixer

Input signal power detection

Emergency stop for downstream analog circuitry

protection

FIFO error detection

The AD9142 is a dual, 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.

The AD9142 TxDAC+® includes features optimized for direct

conversion transmit applications, including complex digital mod-

ulation, input signal power detection, and gain, phase, and offset

compensation. The DAC outputs are optimized to interface

seamlessly with analog quadrature modulators, such as the

ADL537x F-MOD series and the ADRF670x series from Analog

Devices, Inc. A 3-wire serial port interface provides for the pro-

gramming/readback of many internal parameters. Full-scale

output current can be programmed over a range of 9 mA to 33 mA.

The AD9142 is available in a 72-lead LFCSP.

PRODUCT HIGHLIGHTS

1. Advanced low spurious and distortion design techniques

provide high quality synthesis of wideband signals from

baseband to high intermediate frequencies.

2. Very small inherent latency variation simplifies both software

and hardware design in the system. It allows easy multichip

synchronization for most applications.

On-chip numeric control oscillator allows carrier placement

anywhere in the DAC Nyquist bandwidth

Transmit enable function for extra power saving

High performance, low noise PLL clock multiplier

Digital gain and phase adjustment for sideband suppression

Digital inverse sinc filter

3. New low power architecture improves power efficiency

(mW/MHz/channel) by 30%.

4. Input signal power and FIFO error detection simplify

designs for downstream analog circuitry protection.

5. Programmable transmit enable function allows easy design

balance between power consumption and wakeup time.

Supports single DAC mode

Low power: 2.0 W at 1.6 GSPS, 1.7 W at 1.25 GSPS, full

operating conditions

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
