DS90UB935-Q1: 935 schematic review

Sherry Liang

Part Number: DS90UB935-Q1

Dear team,

Could you please help review 935 schematic and 4Gbps POC network? The camera resolution is 1920*1280@60fps, RAW12.

1. They have 5 I/O signal, but we only have 4 GPIOs. For GPIO3, they connect two signals to the GPIO3, one signal VM_ERRB is input signal and the other signal RESET is output signal. Is this feasible?

2. For the ESD, they choose SESD0402X1UN, the I/O capacitor is 0.3pF. Do we have any suggestion to choose ESD?

3. The second attachment is Murata's 4Gbps low cost recommendation. Could you please help review it?

Hi Sherry,

I reviewed the schematic and PoC network as requested and I don't have any comments to make about the schematic. It appears to be very well done. As for the PoC network it looks like one of our recommended solutions and I don't see any issues with it. I would still recommend to test the overall channel to make sure it meets our requirements. Also I see a test point attached to the high-speed trace which concerns me. I would recommend having the least amount of stubs as possible.

Regards,

Nick
