GENERAL DESCRIPTION
The AD9125 is a dual, 16-bit, high dynamic range TxDAC+® digital-to-analog converter (DAC) that provides a sample rate of 1000 MSPS, permitting a multicarrier generation up to the Nyquist
frequency. It includes features optimized for direct conversion transmit applications, including complex digital modulation, and gain and offset compensation.

FEATURES
Flexible CMOS interface allows dual-word, word, or byte load
Single-carrier W-CDMA ACLR = 80 dBc at 122.88 MHz IF
Analog output: adjustable 8.7 mA to 31.7 mA, RL= 25 Ω to 50 Ω
Novel 2×/4×/8× interpolator/complex modulator allows carrier placement anywhere in the DAC bandwidth
Gain and phase adjustment for sideband suppression
Multichip synchronization interface
High performance, low noise PLL clock multiplier
Digital inverse sinc filter
Low power: 900 mW at 500 MSPS, full operating conditions
72-lead, exposed paddle LFCSP
