1. Calculated according to the BCLK frequency as follows:
2. Calculated according to the BCLK frequency as follows:
3. 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
R =1 kΩ, hold time of output “L” level is
t = – 30 pF ✕ 1 kΩ ✕ ln (1 – 0.2 V
