Part Number : AD9773
Function : 0.3-25V; 12-bit, 160MSPS 2x/4x/8x interpolating dual TxDAC+ D/A converter
Package : 80-lead thin quad flat package, exposed pad (TQFP_EP)
Maker : Analog Devices
Pinouts : 
Description :
The AD9773 is the 12-bit member of the AD977x pin compatible, high performance, programmable 2×/4×/8× interpolating TxDAC+® family. The AD977x family features
a serial port interface (SPI) that provides a high level of programmability, thus allowing for enhanced system-level options. These options include selectable 2×/4×/8× interpolation filters; fS/2, fS/4, or fS/8 digital quadrature modulation with image rejection; a direct IF mode; programmable channel gain and offset control; programmable internal clock divider;
straight binary or twos complement data interface; and a single port or dual-port data interface.
The selectable 2×/4×/8× interpolation filters simplify the requirements of the reconstruction filters while simultaneously enhancing the TxDAC+ family’s pass-band noise/distortion
performance. The independent channel gain and offset adjust registers allow the user to calibrate LO feedthrough and side band suppression errors associated with analog quadrature
modulators. The 6 dB of gain adjustment range can also be used to control the output power level of each DAC.
