The AD9958 consists of two DDS cores that provide independentfrequency, phase, and amplitude control on each channel.This flexibility can be used to correct imbalances betweensignals due to analog processing, such as filtering, amplification,or PCB layout related mismatches. Because both channels sharea common system clock, they are inherently synchronized.Synchronization of multiple devices is supported.The AD9958 can perform up to a 16-level modulation offrequency, phase, or amplitude (FSK, PSK, ASK). Modulation isperformed by applying data to the profile pins. In addition, theAD9958 also supports linear sweep of frequency, phase, oramplitude for applications such as radar and instrumentation.The AD9958 serial I/O port offers multiple configurations toprovide significant flexibility. The serial I/O port offers an SPIcompatiblemode of operation that is virtually identical to theSPI operation found in earlier Analog Devices, Inc., DDSproducts. Flexibility is provided by four data pins (SDIO_0 /SDIO_1 / SDIO_2 / SDIO_3) that allow four programmablemodes of serial I/O operation.The AD9958 uses advanced DDS technology that provides lowpower dissipation with high performance.

Each channel has a dedicated 32-bitfrequency tuning word, 14 bits of phase offset, and a 10-bitoutput scale multiplier.The DAC outputs are supply referenced and must be terminatedinto AVDD by a resistor or an AVDD center-tappedtransformer. Each DAC has its own programmable reference toenable different full-scale currents for each channel.The DDS acts as a high resolution frequency divider with theREFCLK as the input and the DAC providing the output. TheREFCLK input source is common to both channels and can bedriven directly or used in combination with an integratedREFCLK multiplier (PLL) up to a maximum of 500 MSPS. ThePLL multiplication factor is programmable from 4 to 20, ininteger steps. The REFCLK input also features an oscillatorcircuit to support an external crystal as the REFCLK source.The crystal must be between 20 MHz and 30 MHz.

The filter has a programmable bandwidth and tunable center frequency. The filter characteristics are highly stable over temperature, supply, and process variation.Single-ended and differential signal interfaces are possible on both input and output terminals, simplifying the connection to other components of the signal chain.

On-chip clock generation produces a mixing signal with a programmable frequency and phase. In addition, the ADA2200 synchronization output signal eases interfacing to other sampled systems, such as data converters and multiplexers.The ADA2200 is available in a 16-lead TSSOP package.
