... Clock Circuit The LAN9215i can accept either a 25MHz crystal (preferred MHz single-ended clock oscillator (±50 PPM) input. The LAN9215i shares the 25MHz clock oscillator input (CLKIN) with the crystal input XTAL1/CLKIN. If the single-ended clock oscillator method is implemented, XTAL2 should be left unconnected and CLKIN should be driven with a nominal 0-3 ...
