Datasheet Analog Devices AD9122BCPZ — Даташит

Dual, 16-Bit, 1230 MSPS,
TxDAC+ Digital-to-Analog Converter
AD9122
The AD9122 TxDAC+В® includes features optimized for direct
conversion transmit applications, including complex digital modulation, and gain and offset compensation. The DAC outputs
are optimized to interface seamlessly with analog quadrature
modulators, such as the ADL537x F-MOD series from Analog
Devices, Inc. A 4-wire serial port interface provides for programming/readback of many internal parameters. Full-scale output
current can be programmed over a range of 8.7 mA to 31.7 mA.
The AD9122 comes in a 72-lead LFCSP. FEATURES
Flexible LVDS interface allows word, byte, or nibble load
Single-carrier W-CDMA ACLR = 82 dBc at 122.88 MHz IF
Analog output: adjustable 8.7 mA to 31.7 mA,
RL = 25 О© to 50 О©
Integrated 2Г—/4Г—/8Г— interpolator/complex modulator allows
carrier placement anywhere in the DAC bandwidth
Gain, dc offset, and phase adjustment for sideband
suppression
Multiple chip synchronization interfaces
High performance, low noise PLL clock multiplier
Digital inverse sinc filter
Low power: 1.5 W at 1.2 GSPS, 800 mW at 500 MSPS,
