Hi,

I am using TDA4VM-Q1 processor and I'd like to evaluate the processor's MIPI D-PHY(CSI-2) Eye-diagram.

Could you please share the processor receiver eye mask details to evaluate our PCB.

Thank you.

Hi,

D-PHY Electrical Characteristics are compliant with MIPI DPHY v1.2 dated August 1, 2014 including ECNs and Errata as applicable. Please refer to the MIPI DPHY specification for more details.

Thanks for your reply.

Don't you have any eye mask which is specified by TI for TDA4VM?

Jihoon,

No we do not have standalone eye mask specified for TDA4VM. In case you do not have the spec, the eye mask is defined as

Height: 80 mVppd

Width: ~0.5 UI (allow 5% range of 0.5 UI to 0.525 UI)

Thanks for your reply.

I will understand the spec that you defined to me is a general spec
