8K Ultra HD Display Visual Processing Solution

Electronic component brands supplied by Zhongtian Ke Gong Semiconductor for use in this solution:

Richtek, SK Hynix, TI (Texas Instruments), Coilcraft, Murata, YXC (Yangxing) Crystal Oscillators

1. 1.8K video SoC/GPU/AI computing power consumption surges, resulting in high instantaneous peak currents and severe transient load fluctuations;

2. HDMI 2.1/DP 1.4 48 Gbps high-speed signals are extremely sensitive to power supply ripple and noise, making them prone to horizontal lines and screen distortion;

3. Large-screen LED backlights feature multiple drive channels and high power consumption, requiring multi-channel, high-precision constant-current dimming;

4. The entire system involves multiple voltage rails (core, graphics memory, DDR, panel, backlight, interfaces), with a compact layout and stringent thermal management requirements;

5. Industrial and automotive applications require wide temperature ranges, AEC-Q100 automotive-grade compliance, and multiple safety protection mechanisms.

This solution covers the complete chain, including the AC-DC front-end for the entire system, multi-phase PMICs for SoCs, high-current POLs for graphics memory, bias power supplies for LCD/OLED panels, multi-channel LED backlight drivers, and LDO protection for high-speed interfaces, and is perfectly compatible with the Xilinx Zynq 8K vision processing platform and professional 8K video processors.
