GENERAL DESCRIPTION

The AD9777 is the 16-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)

providing a high level of programmability, thus allowing for

enhanced system level options. These options include: selectable

2×/4×/8× interpolation filters; f_S/2, f_S/4, or f_S/8 digital quadrature

modulation with image rejection; a direct IF mode; programmable

channel gain and offset control; programmable internal clock

divider; straight binary or two’s complement data interface; and

a single-port or dual-port data interface.

Two’s Complement/Straight Binary Data Coding

Dual-Port or Single-Port Interleaved Input Data

Single 3.3 V Supply Operation

Power Dissipation: Typical 1.2 W @ 3.3 V

On-Chip 1.2 V Reference

The selectable 2×/4×/8× interpolation filters simplify the require-

ments 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 sideband suppression
