500 MSPS Direct Digital Synthesizer

with 10-Bit DAC

AD9911

FEATURES

Patented SpurKiller technology

GENERAL DESCRIPTION

The AD9911 is a complete direct digital synthesizer (DDS).

This device includes a high speed DAC with excellent wideband

and narrowband spurious-free dynamic range (SFDR) as well as

three auxiliary DDS cores without assigned digital-to-analog

converters (DACs). These auxiliary channels are used for spur

reduction, multitone generation, or test-tone modulation.

Multitone generation

Test-tone modulation

Up to 800 Mbps data throughput

Matched latencies for frequency/phase/amplitude changes

Linear frequency/phase/amplitude sweeping capability

Up to 16 levels of FSK, PSK, ASK

Programmable DAC full-scale current

32-bit frequency tuning resolution

14-bit phase offset resolution

10-bit output amplitude-scaling resolution

Software-/hardware-controlled power-down

Multiple device synchronization

Selectable 4× to 20× REF_CLK multiplier (PLL)

Selectable REF_CLK crystal oscillator

56-lead LFCSP

The AD9911 is the first DDS to incorporate SpurKiller

technology and multitone generation capability. Multitone

mode enables the generation up to four concurrent carriers;

frequency, phase and amplitude can be independently

programmed. Multitone generation can be used for system

tests, such as inter-modulation distortion and receiver blocker

sensitivity. SpurKilling enables customers to improve SFDR

performance by reducing the magnitude of harmonic

components and/or the aliases of those harmonic components.

APPLICATIONS

Agile local oscillator

Test and measurement equipment

Commercial and amateur radio exciter

Radar and sonar

Test-tone generation

Fast frequency hopping

Clock generation

Test-tone modulation efficiently enables sine wave modulation

of amplitude on the output signal using one of the auxiliary

DDS cores.

The AD9911 can perform modulation of frequency, phase, or

amplitude (FSK, PSK, ASK). Modulation is implemented by

storing profiles in the register bank and applying data to the

profile pins. In addition, the AD9911 supports linear sweep of

frequency, phase, or amplitude for applications such as radar

and instrumentation.
