Differential Signal Impedance Control (100\u03a9)<\/strong><\/p>\n\n\n\n<p><strong>Trace Rules:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A 1:1 differential pair width\/space ratio is recommended, with intra-pair error \u2264 5 mil and inter-pair error \u2264 10 mil.<\/li>\n\n\n\n<li>Trace spacing (s) must meet the following requirements: <code>s &lt; h<\/code> (dielectric thickness), <code>s &lt; W<\/code> (line width), and <code>d &gt; 2s<\/code> (distance from other traces).<\/li>\n\n\n\n<li>Use a 2D field solver to accurately calculate impedance, avoiding reliance on empirical values.<\/li>\n<\/ul>\n\n\n\n<p><strong>Via Design:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use small vias (8 mil\/16 mil recommended) to reduce capacitance effects and impedance drop.<\/li>\n\n\n\n<li>Avoid switching high-speed signals across different layers; otherwise, additional return vias will be required.<\/li>\n<\/ul>\n\n\n\n<p><strong>3. Power Supply and Decoupling Capacitor Design<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Power Inlet:<\/strong> Place a 10\u03bcF tantalum capacitor for voltage regulation.<\/li>\n\n\n\n<li><strong>Chip Power Supply: <\/strong>Place a 0.1\u03bcF or 0.01\u03bcF ceramic capacitor next to each high-speed chip, and connect the capacitor pins with double vias to reduce inductance.<\/li>\n\n\n\n<li><strong>Decoupling Capacitors: <\/strong>Configure at least one 4.7\u03bcF capacitor and five 0.1\u03bcF capacitors, connecting them directly to the power plane (minimizing the path).<\/li>\n\n\n\n<li><strong>Power Plane: <\/strong>Avoid signal lines crossing split planes to ensure a continuous return path.<\/li>\n<\/ul>\n\n\n\n<p><strong>4. EDID Management Strategy<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>EDID Compose Mode: Automatically analyzes the resolutions of all displays and selects the lowest compatible value (e.g., 1080P) to ensure compatibility.<\/li>\n\n\n\n<li>Fixed Mode: Forces the output to a specific resolution (e.g., 4K@60Hz) to accommodate high-end devices. <\/li>\n\n\n\n<li>Priority Setting: Supports port priority (for example, when Output 1 is disconnected, Output 2 defaults to 1080P)<\/li>\n<\/ul>\n\n\n\n<p><strong>5.
