DS90UB964-Q1: What is its maximum CSI-2 output bandwidth per port

Part Number: DS90UB964-Q1

Hi team

I would like to ask that what is the maximum CSI-2 output bandwidth per each port? Could it reach to 1.6Gbps*4lane=6.4Gbps per port? I only know about the 960 (3.328Gbps) and 962 (2.528Gbps) while do not know the bandwidth of 964. In addition, could 953 pair with 964 since I have found different answers on the E2E forum, thank you!

Hello Zirui,

Calculating the CSI-2 output bandwidth requires other information as well (for example clock type). I recommend that you watch this video: https://training.ti.com/csi-2-aggregation-breakdown?context=1134310-1139225-1148220 to learn more about CSI-2 output bandwidth calculations.

As for the 953, yes it can pair with the 964, but only in DVP mode, which is a backwards compatibility feature. You can read more the 953 DVP mode in this application note: https://www.ti.com/lit/an/snla270a/snla270a.pdf?ts=1631579362278&ref_url=https%253A%252F%252Fwww.google.com%252F

Hope this helps.

Best Regards,
