PRODUCTION DATA
The following calculation shows an example for a Half-VGA display with the following parameters:
Display Resolution: | 480 × 320 | ![]() |
Frame Refresh Rate: | 58.4 Hz | |
Horizontal Visible Pixel: | 480 columns | |
Horizontal Front Porch: | 20 columns | |
Horizontal Sync: | 5 columns | |
Horizontal Back Porch: | 3 columns | |
Vertical Visible Pixel: | 320 lines | |
Vertical Front Porch: | 10 lines | |
Vertical Sync: | 5 lines | |
Vertical Back Porch: | 3 lines | |
Figure 9-1 HVGA Display |
Calculation of the total number of pixel and blanking overhead: | |
Visible Area Pixel Count: | 480 × 320 = 153600 pixel |
Total Frame Pixel Count: | ( 480 + 20 + 5 + 3 ) × ( 320 + 10 + 5 + 3 ) = 171704 pixel |
Blanking Overhead: | ( 171704 – 153600 ) ÷ 153600 = 11.8% |
The application requires the following serial-link parameters: | |
Pixel Clk Frequency: | 171704 × 58.4 Hz = 10 MHz |
Serial Data Rate: | 1-channel mode: 10 MHz × 30 bit/channel = 300 Mbps |
2-channel mode: 10 MHz × 15 bit/channel = 150 Mbps |
