Notes:
1. CLSN must be asserted for a continuous period of 110 ns or more. Assertion for less than 110 ns period may or may
2. RCLK should meet jitter requirements of IEEE 802.3 specification.
3. CLSN assertion before 51.2 s will be indicated as a normal collision. CLSN assertion after 51.2 s will be
