AD9122-EP
AD9122-EP is TxDAC+ Digital-to-Analog Converter manufactured by Analog Devices.
FEATURES Flexible LVDS interface allows word, byte, or nibble load Single-carrier W-CDMA ACLR = 82 d Bc at 122.88 MHz IF Analog output: adjustable 8.7 m A to 31.7 m A Integrated 1x/2×/4×/8× interpolator/plex modulator allows carrier placement anywhere in the DAC bandwidth Gain, dc offset, and phase adjustment for sideband suppression Multiple chip synchronization interfaces High performance, low noise PLL clock multiplier Digital inverse sinc filter Low power: 1.5 W at 1.2 GSPS, 800 m W at 500 MSPS, full operating conditions 72-lead, exposed paddle LFCSP ENHANCED PRODUCT FEATURES Supports defense and aerospace applications (AQEC standard) Military temperature range (such as - 55°C to +105°C) Controlled manufacturing baseline One assembly/test site One fabrication site Enhanced product change notification Qualification data available on request APPLICATIONS Wireless infrastructure W-CDMA, CDMA2000, TD-SCDMA, Wi MAX, GSM, LTE Digital high or low IF synthesis Transmit diversity Wideband munications: LMDS/MMDS, point-to-point GENERAL DESCRIPTION The AD9122-EP is a dual, 16-bit, high dynamic range digital-toanalog converter (DAC) that provides a sample rate of 1130 MSPS, permitting multicarrier generation up to the Nyquist frequency. The AD9122-EP Tx DAC+® includes features optimized for direct conversion transmit applications, including plex digital modulation, and gain and offset pensation. The DAC outputs are optimized to interface seamlessly with analog quadrature modulators, such as the ADL537x F-MOD series from Analog Devices, Inc. A 4-wire serial port interface provides for programming/readback of many internal parameters. Full-scale output current can be programmed over a range of 8.7 m A to 31.7 m A. The AD9122-EP es in a 72-lead LFCSP. Additional application and technical information can be found in the AD9122 data sheet. PRODUCT HIGHLIGHTS 1. Ultralow noise and intermodulation distortion (IMD) enable high quality synthesis of wideband signals from baseband to high...
