Solutions from IDT. The ICS8533I-31 has selectable
differential clock or crystal inputs. The CLK, nCLK pair can accept
most standard differential input levels. The clock enable is
internally synchronized to eliminate runt pulses on the outputs
during asynchronous assertion/deassertion of the clock enable
pin.

-40°C to 85°C ambient operating temperature
Available in both standard (RoHS 5) and lead-free (RoHS 6)
packages
ICS
Guaranteed output and part-to-part skew characteristics make the
ICS8533I-31 ideal for those applications demanding well defined
performance and repeatability.

This is a program I wrote to test the AD conversion speed. However, when I was simulating the hardware, I found that I couldn't enter the timer interrupt. Even changing the DCO clock source didn't wor...
I would like to ask, do I need to add a 164245 between the 5402 and the 5V powered GAL16V8D input? I looked at the chip data and the VIH of the GAL16V8D is 2V....
