DS90UB953-Q1: data rate / I2S

Kai Hsiao

Hi Sir

1. I saw DS90UB953 can support Full HD 1080p 2MP 60-fps ,May I know how to convert data rate ? I would like to confirm how much Mega Pixels that 935 can support

2. May I know TI have MIPI + I2S Serdes solution ?

Thanks

Kai,
please calculate the video bandwidth in your case. For FPD-Link, one spec. to define the data bandwidth is line rate. UB953 has CSI2 bandwidth and FPD-Link line rate, you can refer to the CSI2 bandwidth which is ~3.2Gbps. if the sensor output data throughput can follow within this, then the video data can be transmitted through UB953.
regarding MIPI + I2S, now we have UB940, please check whether it can catch your detailed application need.

best regards,
Steven

Kai,

the isp vendor has this information as video is generated by them. one simple case:

line length x line number x blanking ratio x frame rate x 8bits/byte (line length unit is byte)

best regards,

Steven
