Other Parts Discussed in Thread: LMK01000
HI
In my new design, LMK01000 is used to be a clock buffer for all system clock. I use snau037b as a reference to draw my schematic. I find there are so many decoupling capacitors populated at Vcc power rail--- 14 X 0.1uf +14X 1uf, besides this, there are another 14 X 100pF capacitors are populated at VCC1~VCC14 power rails. i.e. there are 21 pcs capacitors in total for the power decoupling. I want to know whether it is necessary for us to follow it? They are so many that it is hard for PCB layout. Could anyone tell me the reanson why so many capacitors are used? For some normal design rule, only one 100nF capacitor per power pin is required.
Regards
