Product Details
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.
