MII Clocks
The LXT972M Transceiver is the master clock source for data transmission, and it supplies both
MII clocks (RX_CLK and TX_CLK). It automatically sets the clock speeds to match link
conditions.
When the link is operating at 100 Mbps, the clocks are set to 25 MHz.
When the link is operating at 10 Mbps, the clocks are set to 2.5 MHz.
Figure 7
through
Figure 9
show the clock cycles for each mode.
Note:
The transmit data and control signals must always be synchronized to TX_CLK by the MAC. The
LXT972M Transceiver samples these signals on the rising edge of TX_CLK.
