Calculated according to the BCLK frequency as follows:
This standard value shows the timing when the output is off, and does not
show hold time of data bus.
Hold time of data bus varies with capacitor volume and pull-up (pull-down)
resistance value.
Hold time of data bus is expressed in
t = − CR × ln(1 − V
by a circuit of the right figure.
For example, when V
low level is
t = − 30 pF × 1 k Ω × In(1 − 0.2V
Calculated according to the BCLK frequency as follows:
Hold time is equal to or less than 0 ns when the BCLK frequency exceeds 25 MHz.
