GENERAL DESCRIPTION The AD9154 is a quad, 16-bit, high dynamic range digital-to- analog converter (DAC) that provides a maximum sample rate of 2.4 GSPS, permitting multicarrier generation up to the Nyquist frequency in baseband mode. The AD9154 includes features optimized for direct conversion transmit applications, including complex digital modulation, input signal power detection, and gain, phase, and offset compensation. The DAC outputs are optimized to interface seamlessly with the ADRF6720-27 radio frequency quadrature modulator (AQM) from Analog Devices, Inc. In mix mode, the AD9154 DAC can reconstruct carriers in the second and third Nyquist zones. A serial port interface (SPI) provides the programming/readback of internal parameters. The full-scale output current can be programmed over a range of 4 mA to 20 mA. The AD9154 is available in two different 88-lead LFCSP packages. PRODUCT HIGHLIGHTS 1. Ultrawide signal bandwidth enables emerging wideband and multiband wireless applications. 2. Advanced low spurious and distortion design techniques provide high quality synthesis of wideband signals from baseband to high intermediate frequencies. 3. JESD204B Subclass 1 support simplifies multichip synchronization. 4. Small package size with a 12 mm × 12 mm footprint. |
