Description

The AD9957 functions as a universal I/Q modulator and agile upconverter for communications systems where cost, size, power consumption and dynamic performance are critical. The AD9957 integrates a high speed Direct Digital Synthesizer (DDS), a high performance, high speed 14-bit digital to analog converter (DAC), clock multiplier circuitry, digital filters and other DSP functions onto a single chip. It provides for base band up-conversion for data transmission in a wired or wireless communications system. The AD9957 is the third offering in a family of a quadrature digital upconverters (QDUCs), which includes the AD9857 and AD9856. It offers performance gains in operating speed, power consumption and spectral performance. Unlike its predecessors, it also supports a 16-bit serial input mode for I/Q base band data. The device can alternatively be programmed to operate as a single-tone sinusoidal source or as an interpolating DAC. The Reference Clock input circuitry includes a crystal oscillator, a high speed divide-by-two input, and a low noise PLL for multiplication of the reference clock frequency.
