Can CYPD5235 be used a a single port, PD controller without the BB-ReTimer ?

[martyntaylor]

I am working on Intel TGL motherboard and Intel have explicitly said we should use the cypress PD controller

Has anyone else used this part with TGL?

can it be used for a signal port controller ?    I can only find the dual port controller (in stock)

Has anyone used this part without  the Intel the BB-ReTimer ?

I only what USB3 and Alternative mode and do not need the USB4/THT support from this part.

I find this all a bit of a mine field as there are so many variants (CCG1,2,3,4,5,6) and which one will Intel support ?

I have reference deigns for CCG5,6 only but the CCG6 is not available leaving only the CCG5 part I can procure

Thanks Martyn

I am looking forward to some feedback from someone who knows a more about this complicated USB-C port

Hello Martyn,

If you could like to change the part number of PD controller from Dual Ports to Single Port, recommend you use CCG6SF CYPD6127 or CYPD6128 directly. If you are going to use CCG6SF, you could use Ez-PD Host SDK 3.5 example firmware directly. 

If you could like to disable BB re-timer, for tiger platform, you need make sure the signal quality meet the specification. And for CCG6SF need external SBU SWITCH for that. 

Best Regards,
