6 Limitations
The 12 MB/sec data transfer rate can only be possibly achieved in
systems where the 7200 series card is the only device using the
bus, but the speed cannot be guaranteed due to the limited FIFO
depth.
The 7200 series 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 1 MB/sec on systems where 7200 series card is the only
device using the bus.
The largest transfer size (in bytes) 7200 series can perform is 64
MB.
