Wideband communications
LMDS/MMDS, point-to-point
GENERAL DESCRIPTION
The AD9785/AD9787/AD9788 are 12-bit, 14-bit, and 16-bit,
high dynamic range TxDAC devices, respectively, that provide
a sample rate of 800 MSPS, permitting multicarrier generation
up to the Nyquist frequency. Features are included for optimizing
direct conversion transmit applications, including complex
digital modulation, as well as gain, phase, and offset compens-
ation. The DAC outputs are optimized to interface seamlessly
with analog quadrature modulators, such as the ADL537x
family from Analog Devices, Inc. A serial peripheral interface
(SPI) provides for programming and readback of many internal
parameters. Full-scale output current can be programmed over
a range of 10 mA to 30 mA. The AD978x family is manufactured
on a 0.18 μm CMOS process and operates from 1.8 V and 3.3 V
supplies. It is enclosed in a 100-lead TQFP package.
PRODUCT HIGHLIGHTS
1.
Low noise and intermodulation distortion (IMD) enable
high quality synthesis of wideband signals from baseband
to high intermediate frequencies.
2.
Proprietary DAC output switching technique enhances
dynamic performance.
3.
CMOS data input interface with adjustable setup and hold.
4.
Low power complex 32-bit numerically controlled
oscillators (NCOs).
