QI want to check with us if I can use 30pF load capacitors with the crystal as
shown below in UG146 schematic. Is it required to use two 30 pF capacitors or
one would be sufficient?
AThe load capacitance of 30 pF is fine as far as the chip is the concerned.
However, the crystal manufacturer specifications also have to be checked for
load capacitance requirements. Also, when you are using a crystal, load
capacitances have to be used on both the pins-CLKIN and CLKOUT.
