9 years agoHi Tricky,
I have one more question. Does it matter which CLK input (rising edge p, falling edge n) I use, or is the description only for the use as diff pair? I think it doesnt matter when I am using the clk inputs only for an I2C CLK or PCLK, but I will be sure that I am right with my guess. Thanks in advance Jérôme edt: Found it by myself I think: pcg-01018 p.2 quote from clk description : "When these clock input pins are used as single-ended pins, you can disregard the p notation." Also the other way round with the n notation . ^^ Thanks Comm. :) edt2: Another thought about I2C CLK and PCLK. Will it be ok to use adjacent clk inputs as one I2C CLK and the other as PCLK? I2C is less than 1MHz instead of the PCLK. Will there be any strong influence of the PCLK or will it be ok? Regards. Jérôme
