300/309-OUTPUT TFT-LCD SOURCE DRIVER (64 GRAY SCALE)
DESCRIPTION
The
碌
PD16640C is a source driver for TFT-LCD 64-gray scale displays. Its logic circuit operates at 3.3 V and the
driver circuit operates at 3.3 or 5.0 V (selectable). The input data is digital data at 6 bits x 3 dots, and 260,000 colors
can be displayed in 64-value outputs
緯
-corrected by the internal D/A converter and 11 external power supplies.
The clock frequency is 55 MHz MIN.
By switching over the number of outputs between 300 and 309, the
碌
PD16640C can be used in TFT-LCD panels conforming to the SVGA/XGA standards.
