Frequently Asked Questions
What serial bus data rates does the TSB82AA2B support?
It supports 100M, 200M, 400M, and 800M bits/s. It also is compatible with rates up to 786.432M bits/s (S800).
How does the device handle large bus latencies?
It implements deep transmit and receive FIFOs (5K Async / 2K Iso for TX; 2K Async / 2K Iso for RX) to buffer data, preventing overruns due to latency.
Is the TSB82AA2B suitable for critical applications?
No. It is neither designed nor intended for use in safety-critical/military/aerospace environments unless specifically designated by TI as compliant or military-grade.
What kind of PCI interfaces are available?
It supports 33-MHz/64-Bit and 33-MHz/32-Bit selectable PCI Interfaces.
