YPbPr and RGB + Csync output
CH7034B supports both RGB+Csync and HDTV YPbPr output format. The resolution is from 480P to 720P and
1080i and 1080P. In RGB+Csync output format, the Csync high level is the same with AVDD power supply. Csync
pin is a COMS push-pull output pin, customer can use other circuit to change is high level to 0.7V or other voltage
level according to different Receivers. ( Refer to Figure 9)
VGA output
VGA standard output signal level of Hsync and Vsync is more than 2.4V. CH7034B Hsync and Vsync output signal
level is same with AVDD power supply. Customer can use 74ACT08 (AND GATE) to pull high this signal level to
5V(recommend to add the diode).. It is recommended but not necessary. ( Refer to Figure 9)
