When implementing the MIPI D-PHY v3.1 IP (Rev. 1) (Transmitter side) for 7 Series with the OBUFTDS option enabled, why do we observe that the HS-PREPARE length can violate the MIPI D-PHY specification rev1.1?
The MIPI D-PHY 4lane@600Mbps with the OBUFTDS option enabled will have HS_PREPARE of approximately 150ns. (out-of-spec)
(According to the MIPI D-PHY specification, the HS_PREPARE max value is 85ns+6UI)
This issue occurs in the MIPI D-PHY (Transmitter side) for 7 Series generated from:
This issue occurs in the MIPI D-PHY for 7 Series, but only when generated with the OBUFTDS option enabled for the MIPI D-PHY TX configuration.
Users should update to the latest version of the IP.
