hello community,
I have some questions about AC timing of IPUx_CSI signals.
In datashee of i.MX6DQAEC, it have a timing characteristics of IPU CLK and DATA.
Which is a correct answer to major a each parameters.
1) Is start point of Tsu
1-1) center of the IPU_CSI_DATA signal? (OVDD*0.5)
1-2) Vih or Vil of the IPU_CSI_DATA signal? (OVDD*0.7) or (OVDD*0.3)
2) Is end of Tsu
2-1) center of the IPU_CSI_CLK signal? (OVDD*0.5)
2-2) Vih or Vil of the IPU_CSI_CLK signal? (OVDD*0.7) or (OVDD*0.3)
3) Is start point of Thd
3-1) center of the IPU_CSI_CLK signal? (OVDD*0.5)
3-2) Vih or Vil of the IPU_CSI_CLK signal? (OVDD*0.7) or (OVDD*0.3)
4) Is end point of Thd
3-1) center of the IPU_CSI_DATA signal? (OVDD*0.5)
3-2) Vih or Vil of the IPU_CSI_DATA signal? (OVDD*0.7) or (OVDD*0.3)
I am looking forward to hearing from you.
Best regards,
Ishii.
refer to the figure, tsu starts valid data signal, end referenced from a low-to-high transition of the pixel clock for 2:1, for CSI should be different mode, like gated mode, non-gated mode, for different mode, one can refer to the Reference Manual to get detailed information.
Hello Joan,
Thank you for your response.
I will refer the Reference Manual to understand a detail of each mode.
Best regards,
Ishii.
