EXT.R IN EXT.G IN EXT.B IN
Input terminals for EXT RGB signals. The signals are clamped by capacitors, therefore the input impedance should be low, 100 ohms or less is recommended. For this input, the brightness and RGB contrast is adjustable, the ABL/ACL limits the output level. This ABL/ACL may be turned On and OFF. OFF : for small area like OSD ON : for large area like TELETEXT (input level 0.7Vp-p/100IRE) The GND terminal for Y/C circuit. Terminals for R/G/B signal output. Connect resistances to GND, for the current source if the slew rate is not enough. Due to the source current limitation, the resistances should be 2.0 or more.
