The GX3232’s input channels are sampled sequentially at a maximum aggregate rate of 300 KS/s. Sampled data is accessed via the PCI bus and a 32 K-sample FIFO buffer. Scanned channels can be set for 2, 4, 8, 16, or 32 channels per scan with the sample clock being generated by one of two internal rate generators which employ 16-bit programmable dividers. The four output channels can be clocked at rates up to 300 KS/s and like the input channels, offer programmable ranges. Each output channel includes a dedicated 16-bit D/A converter with output data being clocked from a 32 K sample FIFO buffer, which interfaces to the PCI bus. Output clocking is generated by one of two internal rate generators which employ 16-bit programmable dividers. Sync input and sync output lines are also provided for synchronizing the input and output signals to an external event. These signals are not accessible at the TS-700’s receiver interface.
