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 for 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, and amplitude).
