AD9102BCPZ

AD9102 TxDAC® and waveform generator is a high performance digital-to-analogue converter (DAC) integrating on-chip pattern memory for complex waveform generation with a direct digital synthesizer (DDS). The DDS is a 14bit output, up to 180MSPS host clock sine wave generator with a 24bit tuning word, allowing 10.8Hz/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. Application includes medical instrumentation, portable instrumentation, signal generators, arbitrary waveform generators, automotive radar.
