Quad, 16-Bit, 2.8 GSPS, TxDAC+® Digital-to-Analog Converter
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.
- 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.
- Wireless communications
3G/4G W-CDMA base stations
Software defined radios
- Wideband communications
Local multipoint distribution service (LMDS) and multichannel multipoint distribution service (MMDS)
