The AD9135/AD9136are dual, 11-/16-bit, high dynamic range digital-to-analog converters (DACs) that provide a maximum sample rate of 2800 MSPS, permitting a multicarrier generation over a very wide bandwidth. The DAC outputs are optimized to interface seamlessly with theADRF6720, as well as other 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. The full-scale output current can be programmed over a typical range of 13.9 mA to 27.0 mA. The AD9135/AD9136 are available in an 88-lead LFCSP.Product HighlightsGreater than 2 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 a 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.ApplicationsWireless communications3G/4G W-CDMA base stationsWideband repeatersSoftware defined radiosWideband communicationsPoint to pointLocal multipoint distribution service (LMDS) and multichannel multipoint distribution service (MMDS)Transmit diversity, multiple input/multiple output (MIMO)InstrumentationAutomated test equipment
