1 The total power dissipated by the HVDD (or RGVDD) supply can be approximated as follows: Total HVDD Power = [CLOAD × HVDD × Pixel Frequency] × HVDD.

Reducing the capacitive load and/or reducing the HVDD supply reduces the power dissipation. CLOAD is the total capacitance seen by all H-outputs.

2 LDO should be used to supply only AVDD and DVDD.

CHANNEL-TO-CHANNEL SPECIFICATIONS

X = A = B, TMIN to TMAX, AVDD_X = DVDD_X = 1.8 V, fCLI = 65 MHz, typical timing specifications, unless otherwise noted.
