SM4TXC/SM4REFCLK
I/O
4
MAC4 Switch MII transmit clock:
Input: SW4-MII MAC mode clock.
Input: SW4-RMII reference clock, please also see the strap-in pin
P1LED1 for the clock mode and normal mode.
Output: SW4-MII PHY modes.
38
VDDIO
P
3.3V, 2.5V or 1.8V digital VDD for digital I/O circuitry.
39
SM4RXC
I/O
4
MAC4 Switch MII Receive clock:
Input: SW4-MII MAC mode.
Output: SW4-MII PHY mode.
Output: SW4-RMII 50MHz reference clock (the device is default clock
mode, the clock source comes from X1/X2 pins 25MHz crystal).
When set the device as normal mode (the chip’s clock source comes
from SM4TXC), the SM4RXC reference clock output should be
disabled by the register 87. Please also see the strap-in pin P1LED1
for the selection of the clock mode and normal mode.
