16-BIT 2.0GSPS QUAD DAC 10GBPS JESD204B

AD9144 DAC Evaluation Board 2.8GSPS

EVAL BOARD, AD9144 16BIT HIGH SPEED DAC

The AD9144 is a quad, 16-bit, high dynamic range digital-to-analog 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 ADRF672x analog quadrature modulators (AQMs) from Analog Devices, Inc. An optional 3-wire or 4-wire serial port interface (SPI) provides for programming/readback of many internal parameters. Full-scale output current can be programmed over a typical range of 13.9 mA to 27.0 mA. The AD9144 is available in an 88-lead LFCSP. PRODUCT HIGHLIGHTS Greater than 1 GHz, ultrawide complex signal bandwidth enables emerging wideband and multiband wireless applications. Advanced low spurious and distortion design techniques provide high quality synthesis of wideband signals from baseband to high intermediate frequencies. JESD204B Subclass 1 support simplifies multichip synchronization in software and hardware design. Fewer pins for data interface width with serializer/ deserializer (SERDES) JESD204B eight-lane interface. Programmable transmit enable function allows easy design balance between power consumption and wake-up time. Small package size with 12 mm × 12 mm footprint. APPLICATIONS 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
