3-2 E06070D0A :
Video signal conversion IC
for TFT-LCD
(1) Scope
The E06070D0A provides a fast, 10bit latched decimating
digital input, which drives 6
channel high voltage drive outputs. Flexible digital input for-
mats, allow several
L3E06070D0As to be used in parallel for higher resolution
displays.
<Feature>
(1) Operation clock frequency :85 MHz
(2) 10-bit digital video signal input
(3) Digital serial parallel conversion (6-ch output)
(4) Built-in D/A converter (10 bit)
(5) Built-in amplifier for video signal polarity inversion
(6) High slew rate output: Typ. 265 V/µs (can drive a TFT
panel directly)
(7) Wide output dynamic range of 1.5 to 13.5 V
(8) Built-in function for switching scan direction
(9) Low power consumption
