Hi all,

I have to do routing between a pic micro controller and an ade7758 energy measuring chip. They communicate using SPI and the master clock is 1MHz. What kind of precautions do I have to take ?

Please help me to decide max track length, width, termination (Using pull down resistors or caps) etc

These two chips are optically isolated using a 6n137 opto isolator. Can it handle such high frequency communication ? (It says 10MBit/s but does anyone have experience with this IC?)

Thanks in advance !!!!!!!!!!!!!!!
 

Some PCB design links.
1MHz shouldn't give you to much trouble, though high speed is determined by rise time of signals not the ultimate clock frequency.
