Figure 25. Media Local Bus (MLB) Timing
4.14.8
Fast Ethernet Interface
MII signals use CMOS signal levels compatible with devices operating at either 5.0 V or 3.3 V. Signals are not TTL compatible.
They follow the CMOS electrical characteristics.
4.14.8.1
MII Receive Signal Timing (RXD[3:0], RX_DV, RX_ER, and RX_CLK)
The receiver functions correctly up to a RX_CLK maximum frequency of 25 MHz +1%. There is no minimum frequency
requirement. In addition, the system clock frequency must exceed four times the RX_CLK frequency.
1 The Controller can shut off MLBCLK to place MLB in a low-power state.
2 Pulse width variation is measured at 1.25 V by triggering on one edge of MLBCLK and measuring the spread on the other
edge, measured in ns peak-to-peak (ns p-p).
3 The board must be designed to insure that the high-impedance bus does not leave the logic state of the final driven bit for this
time period. Therefore, coupling must be minimized while meeting the maximum capacitive load listed.
