AD9142-M5375-EBZ中文资料亚德诺数据手册PDF规格书

GENERAL DESCRIPTION

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.

FEATURES

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

fS/4 power saving coarse mixer

Input signal power detection

Emergency stop for downstream analog circuitry

protection

FIFO error detection

On-chip numeric control oscillator allows carrier placement

anywhere in the DAC Nyquist bandwidth

Transmit enable function for extra power saving
