HX8347-G(T)240RGB x 320 dot, 262K color, TFT Mobile Single Chip Driver5.5 OscillatorDATA SHEET Preliminary V01The HX8347-G can oscillate an internal R-C oscillator for internal operation. Becausethe tolerance of internal oscillator frequency is ±5%, RADJ [3:0] bits for initial2.75MHz internal clock generation. With other dividers setting, the 2.75MHz internalclock can be used to generate clock for other part of the chip using.DOTCLKRGB Display ModeDIV[1:0]Internal Display ModeDisplayControllerOscillatorClock2.7575MHzRADJ[3:0]foscFrequencyDivider 1FS0[1:0]Step up Circuit 1( for DDVDH)DOTCLK/2RGB Display ModeFrequencyDivider 2FS1[1:0]Step up Circuit 2( for VGH,VGLVGL)Step up Circuit 3( for VCL)Figure 5.27: HX8347-G internal clock circuitPWM_CLK(for Backlight CABC)5.6 Source driverThe HX8347-G contains a 720 channels of source driver (S1~S720) which is used fordriving the source line of TFT LCD panel. The source driver converts the digital datafrom GRAM into the analog voltage for 720 channels and generates correspondinggray scale voltage output, which can realize a 262K colors display simultaneously.Since the output circuit of this source driver incorporates an operational amplifier, apositive and a negative voltage can be alternately outputted from each channel.5.7 Gate driverThe HX8347-G contains a 320 gate channels of gate driver (G1~G320) which is usedfor driving the gate. The gate driver level is VGH when scan some line, VGL the otherlines.Himax ConfidentialFor Go-tek OnlyThis information contained herein is the exclusive property of Himax and shall not be distributed, reproduced, or disclosedin whole or in part without prior written permission of Himax.-P.78-October, 2009
