Auto-adjustment circuit for collision detection of ethernet |
摘要 |
A circuit for collision detect of ethernet mainly includes a comparator, a controlling logic, level adjusters, collision counters and a packed length detector. The collision counter is used to detect a collision frequency of Ethernet data transmission. When the collision detector makes any error in collision detection, the controlling logic will drive the level adjusters to adjust the collision level signal up or down to provide more accurate collision detection. An additional packet length detector is used for detecting the length of data packets, so that abnormal short packets can be detected and, if so, a collision signal can be sent in the network.
