The AD6633 synthesizes multicarrier and multistandard digital signals to drive the DAC(s) with up to six wideband modulated carriers from a single output port. Each channel includes an internal peak-to-average power reduction block that reduces power amplifier (PA) power dissipation. The user-configurable interpolating filter (RCF) provides multirate processing (including resampling) and malleable FIR filter characteristics. An all-pass phase equalizer designed to comply with the cdma2000 standard follows the RCF. Each channel has its own 32-bit numerically-controlled oscillator (NCO) to up-convert the filtered/interpolated data to the first IF. Interpolation, antiimage filtering, all-pass equalization, and NCO tuning functions are combined in a single, cost-effective device. Digital IF signal processing provides repeatable manufacturing, higher accuracy, and more flexibility than comparable high dynamic range analog designs. The AD6633 uses a 3.3 V I/O power supply and a 1.8 V core power supply. Typical power consumption is 75 mW per channel or 1.4 W for the complete device. All I/O pins are 5 V tolerant. All control registers and coefficient values are programmed through a generic 16-bit microprocessor interface or a SPI/SPORT-compatible serial port. Intel and Motorola microprocessor bus modes are supported. All inputs and outputs are LVCMOS-compatible. For more information about the AD6633, contact Analog Devices via email at GAIN[2:0]
