你好,
如题,vga输入720p@60hz(电脑1280*720)经过tvp7002输出20bit,YCbCr 4:2:2 , ES
write_byte(0xB8, 0x05,0x06);// Clamp Start
write_byte(0xB8, 0x06,0x10);// Clamp Width
write_byte(0xB8, 0x0F,0x2E);// H-PLL and Clamp Control (default)
write_byte(0xB8, 0x10,0x58);// SOG门限 Sync On Green Threshold, RGB clamp
write_byte(0xB8, 0x11,0x40);// Sync Separator Threshold
write_byte(0xB8, 0x12,0x01);// H-PLL Pre-Coast
write_byte(0xB8, 0x13,0x00);// H-PLL Post-Coast (default)
write_byte(0xB8, 0x1A,0xC2);// Input Mux Select 2, SOG LPF bypassed, 4.8MHz CLP LPF, EXT REFCLK, HSYNC_A and VSYNC_A selected
write_byte(0xB8, 0x26,0x80);// ALC Enable (default)
write_byte(0xB8, 0x28,0x53);// ALC Filter (default)
write_byte(0xB8, 0x2A,0x87);// Fine Clamp Control, CM offset enabled, fine clamp enabled
write_byte(0xB8, 0x2B,0x00);// Power Control (default), SOG ON
write_byte(0xB8, 0x31,0x5a);// ALC Placement
write_byte(0xB8, 0x34,0x07);// Macrovision Stripper Width use 07h if internal REFCLK is used
write_byte(0xB8, 0x35,0x10);// VSYNC Alignment
write_byte(0xB8, 0x36,0x00);// Sync Bypass (default)
write_byte(0xB8, 0x3D,0x06);// Line Length Tolerance (Pixel Tolerance)
write_byte(0xB8, 0x3F,0x00);// Video Bandwidth Control (default), maximum B/W selected
