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 cannot 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 can-
not 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.
