TAXIchip Integrated Circuits (Transparent Asynchronous Xmitter-Receiver Interface)

Advanced Micro Devices 

AMD

Board #4 failed on another occasion after the errors indicated above, but this failure was

due to a power supply failure. Failure time was subtracted from the total run time, and

errors were not indicated in the total. Also, boards #2 and #4 ran over 1,000 hours each

without any error after the only noted error occurrence.

CONCLUSION

The fives sets of TAXI Transmitters and Receivers have run a sum total of 7,000 hours

(3.15 x 1014 bytes) with two error events.

TAXI K2 board includes both TAXI TX and TAXI RX. Each half may be used independently or with other

boards with matching ROM data patterns. For the test described above, FDDI DDJ ROM patterns were used.
