Hi,
I would use SN75DPHY440SS, and I have two questions.
the conditions are 1600x1200 , 20fps , output format:YCbCr4:2:2, MIPI-CSI 2lane
Q1)
Is there a rule of thumb that the DPHY440 should be used when the length of the cable (1) or the wiring length L from the camera to the MPU is more than XXX centimeters?
Or, with the resolution and frame rate of the camera used this time, the datarate is 307.2Mbps/lane, and it is not so high, so is there no necessity to use DPHY440?
Frequency calculation
the conditions are 1600x1200 2byte/pix 20fps
1600x1200x2x20x8=614.4Mbps
the num of data lane is 2
614.4Mpbs/2=307.2Mbps/lane
mipi clock is DDR
307.2/2=153.6MHz
Q2)
In the case of the configuration,My Application, which should be the mounting position of DPHY440, A position or B position?
Is it the position of A from the figure of "Typical Application" described in the data sheet sn75dphy440ss.pdf?
