The TMDS181x is a digital video interface (DVI) or high-definition multimedia interface (HDMI™) retimer. The TMDS181x supports four TMDS channels, audio return channel (SPDIF_IN/ARC_OUT), and digital display control (DDC) interfaces. The TMDS181x supports signaling rates up to 6 Gbps to allow for the highest resolutions of 4k2k60p 24 bits per pixel and up to WUXGA 16-bit color depth or 1080p with higher refresh rates. The TMDS181x can be configured to support the HDMI2.0a standard. The TMDS181x automatically configures itself as a redriver at low data rate (<1.0 Gbps) or as a retimer above this data rate. Redriver mode supports HDMI1.4b with data rates up to 3.4 Gbps
The TMDS181x supports dual power supply rails of 1.2 V on VDD and 3.3 V on VCC for power reduction. Several methods of power management are implemented to reduce overall power consumption. TMDS181x supports fixed receive EQ gain or adaptive receive EQ control by I2C or pin strap to compensate for different lengths input cable or board traces.

TIDA-050001 — HDMI 2.0 ESD 保護參考設計
此參考設計展示兩種不同的方式，以保護 HDMI 2.0 驅動器與重定時器的 TMDS 線路，使其免受靜電放電 (ESD) 影響。HDMI 標準適用於從機上盒到筆記型電腦到電視的多項應用領域。由於這些連接埠始終是外部埠，因此容易受到 ESD 事件的影響。高速 HDMI 2.0 訊號代表驅動器無法在 IC 中整合良好的 ESD 防護，因此需要離散式 ESD 防護裝置。HDMI 驅動器通常也非常敏感，這表示 ESD 保護必須具有超低鉗位。此設計會檢查兩種設定的初始 HDMI 2.0 規範資料，每塊電路板上執行的 ESD 測試和測試後的最終 HDMI 2.0 規範資料。如需有關保護 HDMI (...)
