The AD9102 TxDAC and waveform generator is a high performance digital-to-analog converter (DAC) integrating on-chip pattern memory for complex waveform generation with a direct digital synthesizer (DDS).
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.
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.
A gain adjustment factor and an offset adjustment are applied to the digital signal on their way into the DAC.
The AD9102 offers exceptional ac and dc performance and supports DAC sampling rates of up to 180 MSPS.
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.

Markets and Technologies
Product Lifecycle Production
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
Evaluation Kits (1)
The AD9106 and AD9102 evaluation boards are compatible with ARM-based Mbed-enabled boards like SDP-K1 and are designed to connect to Arduino Uno headers.
The evaluation setup can be powered by USB only and does not require a high-frequency waveform generator for clock input. The evaluation board by default uses an on-board 156.25 MHz crystal oscillator as clock source but provides external clocking option. DAC outputs can be transformer-coupled or evaluated with on-board amplifiers.
Along with the hardware, example source codes are provided and can be used as starting point for developing firmware for targeted applications. The evaluation boards and the example source codes with minor changes can work with other Mbed platforms.
Features & Benefits
- 180 MSPS 14-bit single digital-to-analog converter with SPI interface
- Balun or amplifier options for differential to single-ended output voltage conversion
- On-board and external clocking options
- Small, Arduino Uno form factor
- Can be used with Mbed-enabled hardware like SDP-K1
