For stability, a delay of approximately 180ms is added from the +3.3V o/p to reset
release.
2.1.3 Clock
The LAN9353 requires a fixed-frequency 25 MHz clock (±50 ppm) source for use by
the internal clock oscillator and PLL. This is typically provided by attaching a 25 MHz
crystal to the OSCI and OSCO pins. Optionally, this clock can be provided by driving
the OSCI input pin with a single-ended 25 MHz clock source.
