Notes

1. Frame frequency:

2. VDD unchanged after frequency calibration.

3. Not available at any pad.

4. Decoupling capacitor between VLCDIN and VSS1 is 100 nF. A higher capacitance increases tsu and a higher VDD1,

VDD2 or VDD3 reduces tsu.

5. All timing values are valid within VDD1,VDD2,VDD3 and Tamb ranges and are referenced to VIL and VIH with an input

voltage swing from VSS1 to VDD1.

6. Cb is the total capacitance (in pF) of one bus line.
