FPD33584 Datasheet | National Semiconductor

Description The FPD33584 Column Driver is a direct drive, 64 gray level, 384 output, TFT-LCD column driver with an RSDS™ data interface. It provides the capability to display 262,144 colors (18-bit color) with a large dynamic output range for twisted nematic applications. When used in a bank with other FPD33584 column drivers, the FPD33584 can support XGA (8 drivers) or SXGA (10 drivers) applications. Output voltages are gamma corrected to provide a direct mapping between digital video and LCD panel brightness. The 85MHz operating frequency allows the FPD33584 to meet the requirement of high refresh rate applications (i.e. XGA monitors with a 75Hz refresh rate). An RSDS (Reduced Swing Differential Signaling) interface is used between the timing controller and the column driver to minimize EMI and reduce power. Features n RSDS (Reduced Swing Differential Signaling) data bus for low power, reduced EMI and small PCB foot print n 85MHz maximum operating frequency at VDD1=3.0V (70MHz at VDD1=2.7V) n Pin patible with Samsung S6C0666 n Ideal for XGA and SXGA applications n Supports notebook and monitor applications n Smart Charge Conservation for low power consumption n 64 Gray levels per color (18-bit color) n Supports both Dot and N-Line inversion n Four externally programmable gamma curves n Low offset, High voltage outputs for high contrast in a large range of display panel applications n Optional, high current, repair amplifiers System Diagram © 2003 National Semiconductor Corporation DS200432 .national.
