Voltage on the serial link
I am using this MAX9278 deserializer.
The inputs to the IN+, IN- pins of the deserializer are twisted pair inputs.
On the IN+ and IN- serial link, I have 2 AC coupling capacitors of 220nF 50V on each link and parallel termination resistors of 49.9K…

GMSL Deserializer to LCD Link Rate
I need to calculate the Link Rate for my GMSL Deserializer which is connected to a 800 * 480 TFT Display.
In that case, I stumbled upon this Article
On the last few lines, they are asking to multiply by 30 for RGB666 and 40 for RGB888.
I am not able…

Deserializer Datarate calculation
I am having this MAX9278 deserializer IC.
The input to the pins +IN and -IN is a twisted pair input and therefore, it is a differential signal. I have configured the CX/TP pin to low since it is a twisted pair input to IN+ and IN-. I hope this is…

Coax or STP input to the Deserializer
I have this MAX9278 deserializer.
I am planning to give Shielded Twisted Pair (STP) input to the IN+ and IN- pins of the deserializer instead of COAX input.
Can someone help me to let me know what pins or pin configurations I need to change in the…

Setting the address of Deserializer
I have this MAX9278 GMSL1 Deserializer.
I have 3 below questions:
How to configure the CX/TP pin if I want to use the coax mode?
And how to arrive at the address of the deserializer if I connect both ADD0 and ADD1 as ground? I am not able to…

SPI Configuration in TFT
I have a TFT which requires SPI Communication interface to get it configured.
My questions :
When we say, "configure the tft", what do we actually do? Do we set some bits or erase some bits inside he tft? If so, what purpose do they serve?
The TFT…
