GENERAL DESCRIPTION
The AD9106 TxDAC® and waveform generator is a high perform-
ance quad DAC integrating on-chip pattern memory for complex
waveform generation with a direct digital synthesizer (DDS). The
DDS is a 12-bit output, up to 180 MHz master clock sinewave
generator with a 24-bit tuning word allowing 10.8 Hz/LSB
frequency resolution. The DDS has a single frequency output
for all four DACs and independent programmable phase shift
outputs for each of the four DACs.
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 allows the user to
program the pattern period for all four DACs as well as the start
delay within the pattern period for the signal output on each
DAC channel.
An SPI interface is used to configure the digital waveform
generator and load patterns into the SRAM.
There are gain adjustment factors and offset adjustments
applied to the digital signals on their way into the four DACs.
The AD9106 offers exceptional ac and dc performance and
supports DAC sampling rates up to 180 MSPS. The flexible
power supply operating range of 1.8 V to 3.3 V and low power
dissipation of the AD9106 make it well suited for portable and low
power applications.
