Low Power, 14-Bit, 180 MSPS, Digital-to-Analog

Converter and Waveform Generator

Data Sheet

AD9102

The DDS is a 14-bit output, up to 180 MSPS master clock sine

wave generator with a 24-bit tuning word, allowing 10.8 Hz/LSB

frequency resolution.

FEATURES

On-chip 4096 × 14-bit pattern memory

On-chip DDS

Power dissipation @ 3.3 V, 4 mA output

96.54 mW @ 180 MSPS

Sleep mode: <5 mW @ 3.3 V

Supply voltage: 1.8 V to 3.3 V

SFDR to Nyquist

87 dBc @ 10 MHz output

Phase noise @ 1 kHz offset, 180 MSPS, 8 mA: −150 dBc/Hz

Differential current outputs: 8 mA max @ 3.3 V

SRAM data can include directly generated stored waveforms,

amplitude modulation patterns applied to DDS outputs, or DDS

frequency tuning words.

An internal pattern control state machine lets the user program

the pattern period for the DAC as well the start delay within the

pattern period for the signal output on the DAC .

A SPI interface is used to configure the digital waveform

generator and load patterns into the SRAM.

Small footprint, 32-lead, 5 mm × 5 mm LFCSP with 3.6 mm ×

3.6 mm exposed paddle, and Pb-free package

A gain adjustment factor and an offset adjustment are applied to

the digital signal on their way into the DAC.

APPLICATIONS

The AD9102 offers exceptional ac and dc performance and

supports DAC sampling rates of up to 180 MSPS.

Medical instrumentation

Portable instrumentation

The flexible power supply operating range of 1.8 V to 3.3 V and

low power dissipation of the AD9102 make it well suited for

portable and low power applications.

Signal generators, arbitrary waveform generators

Automotive radar

GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

The AD9102 TxDAC® and waveform generator is a high perfor-

mance digital-to-analog converter (DAC) integrating on-chip

pattern memory for complex waveform generation with a direct

digital synthesizer (DDS).

1. High Integration.

On-chip DDS and 4096 × 14 pattern memory.

2. Low Power.

Power-down mode provides for low power idle periods.
