Hi Sir,
May I know what is the DPHY440SS capability for trace length support?
As my customer design, their MIPI 4 lanes trace length is 62cm Max. from sensor output to the connector.
The Max. data rate is 1.3Gb.
Please help to advise.
Thanks.

Hi,
The DPHY440 can support max data rate of 1.5G, so 1.300Gbps is within the DPHY440 support capability.
The DPHY has both receiver equalizer and transmitter pre-emphasis to compensate the channel ISI loss. Three RX equalization levels are available at 0 dB, 2.5 dB, and 5 dB at 750MHz. Two TX pre-emphasis levels are available at 0dB and 2.5dB. Depending on the channel loss and the placement of the DPHY440, we can use both RX equalizer and TX pre-emphasis to achieve the optimal result.
Do we know the loss of this 62cm trace and the placement of the DPHY440 in their system?
Thanks
David
Hi,
You want to place the DPHY440 away from the TX, closer to the RX.
Thanks
