Greater than 1GHz, 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 subclass1 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
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 to 27.0mA. The AD9144 is available in an 88-lead LFCSP.
