Datasheet Analog Devices AD9146BCPZ

Dual, 16-Bit, 1230 MSPS,
TxDAC+ Digital-to-Analog Converter
AD9146 Data Sheet
FEATURES The AD9146 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 3-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 AD9146 comes in a 48-lead LFCSP. Flexible LVDS interface allows byte or nibble load
Single-carrier W-CDMA ACLR = 80 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— 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
