LogiCORE IP MIPI D-PHY Controller - What is the maximum value of start-up time before High-speed data transfer?

ソリューション

The start-up time is governed by the min (LPX_TIME + HS_PREPARE_TIME + HS_ZERO_TIME) plus CDC flops delay and will vary with the line rate.

• (a) LPX_TIME = Time of LP-01
• (b) HS_PREPARE_TIME = Time of LP-00
• (c) HS_ZERO_TIME = Time of HS-00

Note 1: The value of (a) can be set from the IP wizard. (the default is 50ns)

Note 2: The value of (b)+(c) is stated in the spec (145ns + 10UI) and no control is given to the user for these parameters.
