Calculation of Pixel Clock Rise/Fall Time
The limitation on pixel clock rise time/fall time is not specified. It should be calculated from the hold time
and setup time based on the following assumptions:
Rising-edge latch data
max rise time allowed = (positive duty cycle - hold time)
max fall time allowed = (negative duty cycle - setup time)
In most of case, duty cycle is 50 / 50, therefore:
max rise time = (period / 2 - hold time)
max fall time = (period / 2 - setup time)
For example: Given pixel clock period = 10ns, duty cycle = 50 / 50, hold time = 1ns, setup time = 1ns.
positive duty cycle = 10 / 2 = 5ns
≥ max rise time allowed = 5 - 1 = 4ns
negative duty cycle = 10 / 2 = 5ns
≥ max fall time allowed = 5 - 1 = 4ns
Falling-edge latch data
max fall time allowed = (negative duty cycle - hold time)
max rise time allowed = (positive duty cycle - setup time)
