What will happen if I desolder the 25 MHz clock of an ethernet module (like this one; datasheet of the chip) and add a faster clock (say 100 MHz)? The related product is a 10BASE-T ethernet module. But is the 10 Mbps limit related to the chip or the clock?* In case the limit is not related to the chip, will I get a higher speed, data corruption, ...?
According to Wikipedia 100BASE-TX ethernet uses a 25 MHz clock and 10BASE-T a 2.5 MHz clock so I am actually confused why they use the faster clock for their low speed ethernet controller.
I know that the speed is also related to the encoding. But for my application I actually need the Manchester encoding of 10BASE-T, yet with a higher speed.
