Limitations

The 12MB/sec data transfer rate can only be possibly achieved in systems where the PCI-7200 card is the only device using the bus, but the speed can not be guaranteed due to the limited FIFO depth.

The PCI-7200 supports three input clock modes, internal clock, external clock, and handshaking modes. The first two modes cannot guarantee the input data integrity in high-speed data rate because of the limited FIFO depth and PCI-bus latency variation. The handshaking mode is the only mode that data integrity can be guaranteed. During handshaking, expect 12 MB/sec data rate on average, but the speed is not guaranteed.

The guaranteed data rate with internal clock or external clock mode is 1MB/sec on systems where PCI-7200 card is the only device using the bus.

The largest transfer size (in bytes) PCI-7200 can perform is 64MB.
