CLCD timing characteristics
The characterization timing is done considering an output load of 10 pF on all the
outputs.The operating conditions are in worst case V=0.90 V T=125 °C and in best case V
=1.10 V T= 40° C.
The CLCD has a wide variety of configurations and setting and the parameters change
accordingly. Two main scenarios will be considered, one with direct clock to output (166
