Hi Darash

I am an electronic engineer in LCFC，As for checking the FPD-Link III schematic diagram, due to the short project period, we hope you can help us check it as soon as possible and give us feedback

Hi Darash, One question for you, do we have related design materials such as FAE schematic /PCB layout checklist or something?

If any, you can send to my email steven-yuan@ti.com . Appreciate for that

Hello,

You can look through the supporting documentation on the 960 product page. It will correlate to a 964 design.

Hello Darash,

Could I please have your priority for this request, because it's gating customer's project schedule and 17 days have passed.

Many thanks for your help.

Best regards

Steven

Hi,

Sorry for the delay, I have finished the review please see my comments below.

1. It looks like the 1.1V power supply is labeled as 1V2. Can you confirm this is meant to be 1.1V?

2. It appears that you are missing a 0.01uF cap for each pin.

3. For the MODE strap are you trying to use the CSI strapping? Because this is not supported by 964.

4. For the high-speed path it looks like you are using a CMC with a coax connection which I would recommend against. Also the negative side termination doesn't seem quite right. We recommend 49.9Ohm resistors.

Regards,

Nick
