CPCI-7300

ADLINK's cPCI-7300 are ultra-high speed digital I/O card consisting of 32 digital input/output channels. High performance designs and state-of-the-art technology make these cards ideal for a wide range of applications, such as high-speed data transfer, digital pattern generation and digital pattern capture applications, and logic analyser applications. Trigger signals are available to start the data acquisition of pattern generation.For sustained data transfer directly from or to host memory, the maximum data acquisition rate can be 80 MB/s. The maximum data transfer rates between external device and on board FIFO can be up to 80 MB/s for DO and 160 MB/s for DI. 80MB/s is achieved by 32-bit data width multiplied by an internal 20 MHz clock. 160 MB/s is achieved by 32-bit data width with an external 40 MHz clock for digital input channels only. The cPCI-7300 can reach 160 MB/s throughput only when the acquired data length is less than FIFO size (16 k samples).The cPCI-7300 performs high-speed data transfers between on board FIFO and host memory using bus mastering DMA and scatter gather. When the cPCI-7300 becomes the bus master, it takes control of the PCI/PCIe/cPCI bus, transfers data at burst speed, and then releases the bus. The host memory can be utilized as much as possible to store data when the data acquisition throughput is less than the sustained PCI bus bandwidth.
