S6C0679 PREMILINARY VER 1.0 6 BIT 420 CHANNEL RSDS TFT–LCD SOURCE DRIVER
INTRODUCTION
The S6C0679 is a Source Driver suitable for Reduced Swing Differential Signaling (RSDS) digital interface.
It converts 18-bit digital data into the analog voltage for 420 channels, charging each sub-pixel to the correct gray
level corresponding to the digital value.
The RSDS path to the panel timing controller contributes toward lowering radiated EMI, reducing system power
consumption and eliminates one of the two pixel busses used in typical SXGA+ TFT LCD panels.
This single 9-bit differential bus conveys the 18-bit color data for SXGA+ panels.
FEATURES
• TFT active matrix LCD source driver LSI
• 64 G/S is possible through 10 (5 by 2) external power supply and D/A converter
• Both dot inversion display and N-line inversion display are possible
• Compatible with gamma-correction
• Logic supply voltage: 2.7 to 3.6 V
• LCD driver supply voltage: 7.0 to 10.5 V
• Output dynamic range: 6.8 to 10.3 Vp-p
• Maximum operating frequency: fmax = 65 MHz (internal data transmission rate at 2.7 V operation)
• Output: 420 outputs
• Reduced Swing Differential Signaling (RSDS) digital interface for low power consumption and low EMI.
• Minimum RSDS input swing level (CLKN, CLKP, DATAN, DATAP): 100mV
• Data bus interface control pin (DATPOL)
• TCP or COF available
