DESCRIPTION OF BLOCK DIAGRAM 1. Genesis Chip (Scaler chip) GM5020 (U201) is one chip IC which it supports six function block of Video pre amp, PLL, A/D converter OSD IC, TMDS receiver and scaler. Video signal (0.7Vp.p) clamped through C204, 210, 211 inputs to U201. These R, G, and B analog signals converted to 8bit digital signals through pre amp’s amplifying(1/0.7 time) to match AD converter’s operation range from 0V to 1V and AD converter’s converting analog to 8 bit digital. - Page 13 EEPROM. 1.
