LPC4330 EMC_CLK

Refer to page 595 of the LPC4330 User Manual. Page 595 of the User Manual states that the maximum operating frequency of the EMC_CLK is 120 MHz. Refer to page 123 of the LPC4330 datasheet. The specification for Tcy(clk) (EMC_CLK) is 8.4 nS minimum. This results in a maximum EMC_CLK frequency of 119,047,619 Hz. I have a 12 MHz crystal on our PCBA and was hoping to run the EMC_CLK at 120 MHz. Can I run the EMC_CLK at 120 MHZ without any problems?

For a 120MHz EMC_CLK, the Tcy(clk) should be 8.3333ns minimum.
