HI:
Now I have some problem.
1.What are the ESD measures for COAX input?
Now I have connected 4 COAX cameras to DS90UB964.ESD level:±8KV,330Ω,330PF.A certain camera image collapses.I have now added an ESD tube with a capacitance of 1pF to the ground on the COAX and use copper foil to wrap the PDD-link on the PCB board,But it doesn't seem to be working.So I need new ESD measures.
2.How to configure registers to forcibly switch between internal and external reference clocks?
I have now removed the external reference clock, but the DS90UB964-Q1 still works.I don't understand if this external reference clock works on ds90UB964-Q1.So does this affect the frame synchronization signal?
