IXP46X Product Line of Network Processors
This value is oscillator input. Leave the oscillator output pin as a no-connect.
Where the IXP45X/IXP46X network processors are configured with an input reference-clock, the slew
rate should never be faster than 2.5 V/nS to ensure proper PLL operation. To properly guarantee PLL
operation at the slower slew rate, the Vih and Vil levels need to be met at the 33.33MHz frequency.
These values are typical values seen by the manufacturing process and are not tested.
These parameters are only applicable to signal other than power and ground signals.
It is important to note that when using spread spectrum clocking, other clocks in the system will
change frequency over a specific range. This change in other clocks can present some system level
limitations. Please refer to the application note titled Spread Spectrum Clocking to Reduce EMI
Application Note, when designing a product that utilizes spread spectrum clocking.
