FASTCAT Single-FET for 10Base-T/100Base-TX
Timing Characteristics (Preliminary)
Table 25. MII Management Interface Timing (25 pF Load)
* When operating MDC above 6.25 MHz, MDC must be synchronous with LSCLK and have a setup time of 15 ns and a hold time of 5 ns,
with respect to LSCLK.

Note: MDIO turnaround (TA) time is a 2-bit time spacing between the register address field, and the data field of a frame to avoid drive conten-
tion on MDIO during a read transaction. During a write to the LU6612, these bits are driven to a 10 by the station. During a read, the
MDIO is not driven during the first bit time and is driven to a 0 by the LU6612 during the second bit time.
