AD9144BCPZ

AD9144 is a quad, 16bit TxDAC+® high dynamic range digital-to-analogue converter (DAC) that provides a maximum sample rate of 2.8 GSPS, permitting a multicarrier generation up to the Nyquist frequency. The DAC outputs are optimized to interface seamlessly with the ADRF6720 analogue quadrature modulator (AQM) from Analog Devices, Inc. Full-scale output current can be programmed over a typical range of 13.9mA to 27.0mA. Application includes wireless communications, 3G/4G W-CDMA base stations, wideband repeaters, software defined radios, wideband communications, point-to-point, local multipoint distribution service (LMDS) and multichannel multipoint distribution service (MMDS), transmit diversity, multiple input/multiple output (MIMO), instrumentation, automated test equipment.

• Supports input data rate <gt/>1 GSPS
• Proprietary low spurious and distortion design
• 6-carrier GSM IMD = 77dBc at 75MHz IF, SFDR = 82dBc at dc IF, -9dBFS
• Flexible 8-lane JESD204B interface, support quad or dual DAC mode at 2.8 GSPS
• Multiple chip synchronization, fixed latency
• Data generator latency compensation, low power architecture
