dspstak™ a9248 Two Channel High Speed ADC & DAC I/O Board
The dspstak a9248 is based on an Analog Devices' AD9248 A/D converter. This 14 bit ADC can sample as high 40M/s in single channel mode or 25M/s in dual channel mode. Since both channels are sampled synchronously, the dspstak a9248 is ideal for direct conversion or IF sampling receiver applications.
The dspstak a9248 also includes a stereo sigma delta digital audio DAC (AKM AK4396). The DAC sample rate is programmable for sample rates as high as 216kHz.
The dspstak a9248 takes advantage of the PDAP (parallel data acquisition port) of the third generation SHARC. The PDAP interface acts as a FIFO so that a block of samples can be acquired and then analyzed by the DSP.
The sampling clock is provided by an external clock or may be supplied by a low phase jitter programmable clock. An external trigger input is also available.
One of two input configurations are available. Transformer coupled inputs have lower noise and best isolation. Opamp style inputs (AD8138) are better suited for lower frequency operation and are DC coupled.
SMA connectors are used for all inputs and outputs.
