Reference Clock – Connection and Selection
A crystal or external clock source, such as an oscillator, is used to provide the reference clock for the KSZ8051MNL/RNL.
For the KSZ8051MNL in all operating modes and for the KSZ8051RNL in RMII – 25MHz Clock Mode, the reference clock
is 25 MHz. The reference clock connections to XI (pin 9) and XO (pin 8), and the reference clock selection criteria are
provided in the following figure and table.
