Maximum Transfer Rate of the SX2 Data Bus

Question: What is the maximum transfer rate of the SX2 data bus?



The answer to this question is application specific and is very dependent on the external master's capabilities.
In theory, the host can transfer data at a rate of 53 MBytes/sec. On a system using a PCI card to provide the USB 2.0 interface, the maximum bulk transfer rate is typically 20 Mbytes/sec.
