Part Number:DS90UB954-Q1
Dears:
Customer uses the solution of 954 and 953, there are some issue as follows, pls. help to give some advices:
1. The ground is divided to Analog GND and Digital GND, and use 0 Ohm resistor to connect Analog GND and Digital GND.
However the design is not OK, then use ferrite beads(30 Ohm and 100MHz) is that 953 and 954 can be linked by 10 Meters connecting line.
Q: Can we design a GND and not divide Analog GND and Digital GND?
Q: Is there any requirement about ferrite beads?
Q: Why not use 0 Ohm resistor?
2. Now customer can use 10Meters connecting line to connect 953 and 954, but can not use 15 Meters connecting line.
Q: What need we pay attention to about PCB design? Customer has designed their board according to the datasheet. Is there any other detailed materials about it?
Q: Could you kindly help to provide the PCB files about DS90UB954-Q1EVM?
Q: Customer wants to test the signals to find out issues, is there any testing method to provide us?
Q: The video format is 200W , 12bit and Raw format(30fps), how long can our solution support?
Q: Is there other solution to use 30 Meters or more Meters connecting line between 953 and 954?
Pls. kindly help!
