Note 7.11 Measured at the line side of the transformer, line replaced by 100Ω (+/- 1%) resistor.
The LAN9215i can accept either a 25MHz crystal (preferred) or a 25 MHz single-ended clock oscillator
(±50 PPM) input. The LAN9215i shares the 25MHz clock oscillator input (CLKIN) with the crystal input
XTAL1/CLKIN (pin 6). If the single-ended clock oscillator method is implemented, XTAL2 should be left
unconnected and CLKIN should be driven with a nominal 0-3.3V clock signal. The input clock duty
cycle is 40% minimum, 50% typical and 60% maximum.
It is recommended that a crystal utilizing matching parallel load capacitors be used for the LAN9215i
crystal input/output signals (XTAL1, XTAL2). See
crystal specifications. Refer to application note AN10.7 - “Parallel Crystal Circuit Input Voltage Control”
for additional information.
Note 7.12 The maximum allowable values for Frequency Tolerance and Frequency Stability are

application dependant. Since any particular application must meet the IEEE +/-50 PPM
