Hi everyone,
Thank you for taking the time out to read this post.
My questions is about the decoupling capacitors between Vdd and various chip pins on the PIC32 Ethernet Starter Kit
I understand that you need decoupling capacitors between Vdd and various pins to help smooth out any noise on the Vdd rail.
I'm trying to create my very first design based on the Ethernet Starter Kit, with a few modifications (it's a good learning curve).
If you look at the PIC32 Ethernet Starter Kit Guide here, and scroll to page 22.
You will notice on the Texas Instruments PHY DP83848C (U8) chip that pin 39 is pulled up to Vdd via a 2.2K resistor.
Should Pin 39 on U8 also have a 0.1uF capacitor tied between it and GND?
Is the rule that any chip pin connected to Vdd, even with a pull up resistors or other components should have a decoupling capacitor?
Many thanks,
Rob
