Thank you.
The decoupling path here I mean is Decoupling capacitor for Microcontroller VDD(Power supply rail)
The controller is placed in TOP and the Decoupling capacitors for this controllers VDD rail is present on bottom layer L6
I am debugging a 6 layer board for RE issue and the stackup is (S G G P+G G S).This is a 6 layer board.
The microcontroller is present in TOP(L1) layer and decoupling capacitor is placed in bottom layer(L6).
I was told that "When you decouple through vias, you are always going to get the IO...
I am using DS90UB928Q-Q1 in y design.The output of this IC will be connected to LCD.
The LCD has dedicated Horizontal Sync and Vertical Sync pins.
In the datasheet of DS90UB928Q-Q1 I can see that ,there is no dedicated pins for Horizontal Sync and Vertical Sync.
But in the datasheet I can see...
May I know can I connect multiple ferrite beads in series to improve the impedance.
As per my self study goal of the PoC filter is to make the impedance of the PoC delivery network much higher than the impedance of the 50-ohm transmission line so that the high speed signal edges don't "see"...
Thank you very much I will remove R790.
My maximum load current is 1A only.
The ferrite beads P/N is MPZ2012S102AT000(1 kOhms @ 100 MHz 1 Power Line Ferrite Bead 0805 (2012 Metric) 1.5A 150mOhm).
The two inductors are SRU2016-4R7Y(4.7 µH Shielded Drum Core, Wirewound Inductor 1.15 A 215mOhm...
I am using DS90UB925Q-Q1 5 serializer in my board and output of this board is connected to DS90UB926Q deserializer .The block diagram is given below.
As per theory I can send power along with the data lines(Power-over-Coax Design)
You can see my PoC network in the bottom of the image.
My...
Sorry my mistake.
V_OH ??? (min) = 1.35V
V_OL ??? (max) = 0.45V
I won't be able to share the datasheet because of NDA
1708511003
In this case by default IC will be on and when you turn on the NPN transistor the IC will be off.Please correct me if I am wrong
VDD_MCU_5V is a 5V supply coming from a switcher.
I have two MCUs in the board one with is working at 5V and other at 1.8V
1.8V MCU is used for enabling or disabling the switcher shown here
1.35V ,
1.8V
Not tested yet.This is my first proto.So thought of providing options
Okay good point. Will connect 100K from enable to Ground and microcontroller to other end of 100K
Hope that is fine.Below is my new circuit.
Do I need to connect 100K to GND or 10K is enough
How do I design this pull down resistor
I am using TPS62160QDSGRQ1 in my design. I need to enable and disable it using a microcontroller GPIO and it voltage is 1.8V.
Below is my circuit.
My design calculations are are given below.
May I know your comments
