GENERAL 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 baseband upconversion for data
transmission in a wired or wireless communications system.
The AD9957 is the third offering in a family of quadrature
digital upconverters (QDUCs) that includes the AD9857 and
AD9856. It offers performance gains in operating speed, power
consumption, and spectral performance. Unlike its predecessors,
it supports a 16-bit serial input mode for I/Q baseband data.
The device can alternatively be programmed to operate either 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.
The user interface to the control functions includes a serial port
easily configured to interface to the SPORT of the Blackfin
DSP and profile pins to enable fast and easy shift keying of any
signal parameter (phase, frequency, or amplitude).
