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
