Hello,
I am using the cypress clock generator CY2292F to generate a clock of
25Mhz for my CPLD ( ATF1508 AS). The CY2292F has a load impedance of 15pf , if it is programmed as 3.3volts. The cpld has 10pF input impedance. Now, I am having following problems with the part
- If I program it for 25Mhz then it produces like 13 Mhz. So I have to program it for 50Mhz to generate 25Mhz.
- like an hour after the powerup the cy2292f changed its frequency to
Please advice!
Thanks john
