Is the AD/DA converter Cyclone 3 starter kit compatible

In the Cyclone II -> Features -> Altera's Cyclone II FPGA Interfaces & Protocols Support at the Altera's site is written that SPI and I2C standards can be implemented in Cyclone II devices to provide low-speed communication links between integrated circuits, processors and peripherals.

I've seen in some schematic for Cyclon II board that all I/O pins are LVDS (p/n), which is related to high-speed signaling, as I understood. There were no one pin which is used for SPI or I2C serial interface...

Can anyone advice me? I need 8 digital-to-analog converters (DACs) and 8 ADCs which should work with SPI or I2C interface... For my application, I don't need to use high-speed signals, I need sampling frequency maximal 1MHz (but a few hundreds of kHz will be enough)...

So, in which way should I connect some 8-channel DAC or ADC to the Cyclone II board? Which pins of FPGA should be connected to SPI or I2C pins of DAC/ADC?

Thank in advice!
