Data Sheet Features Very small inherent latency variation: <2 DAC clock cycles Proprietary low spurious and distortion design 6-carrier GSM ACLR = 79 d Bc at 200 MHz IF SFDR > 85 d Bc (bandwidth = 300 MHz) at ZIF Flexible 16-bit LVDS interface Supports word and byte load Multiple chip synchronization Fixed latency and data generator latency pensation 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 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 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 Dual, 16-Bit, 1600 MSPS, Tx DAC+ Digital-to-Analog Converter AD9142 GENERAL DESCRIPTION The AD9142 is a dual, 16-bit, high dynamic range digital-toanalog converter (DAC) that provides a sample rate of 1600 MSPS, permitting a multicarrier generation up to the Nyquist frequency. The AD9142 Tx DAC+® includes Features optimized for direct conversion transmit applications, including plex digital modulation, input signal power detection, and gain, phase, and offset pensation. 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 programming/readback of many internal parameters. Full-scale output current can be programmed over a range of 9 m A to 33 m A. 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...
