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 APPLICATIONS Wireless infrastructure W-CDMA, CDMA2000, TD-SCDMA, WiMAX, GSM, LTE Digital high or low IF synthesis Transmit diversity Wideband communications: LMDS/MMDS, point-to-point Cable modem termination systems 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. 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 allows programming/readback of many inter- nal parameters. Full-scale output current can be programmed over a range of 8.7 mA to 31.7 mA. The AD9125 comes in a 72-lead LFCSP. PRODUCT HIGHLIGHTS 1. Ultralow noise and intermodulation distortion (IMD) enable high quality synthesis of wideband signals from baseband to high intermediate frequencies. 2. A proprietary DAC output switching technique enhances dynamic performance. 3. The current outputs are easily configured for various single-ended or differential circuit topologies. 4. The flexible CMOS digital interface allows the standard 32-wire bus to be reduced to a 16-wire bus. TYPICAL SIGNAL CHAIN NOTES 1. AQM = ANALOG QUADRATURE MODULATOR.
