TDA19995HL Smart HDMI 1.4 (3 : 1) switch with auto-adaptive equalizer

The High-Definition Multimedia Interface (HDMI) switch enables connection of multiple DVI/HDMI inputs to a receiver with at least one input. The TDA19995HL is a switch with three HDMI 1.4 compliant DVI/HDMI inputs and one DVI/HDMI output. Each HDMI input has its own dedicated embedded EDID memory. A fifth DDC-bus input is available for VGA or second HDMI input of SoC. The built-in auto-adaptive equalizer improves signal quality, allowing the use of cable lengths up to 30 m. The TDA19995HL supports Deep Color mode in 10-bit and 12-bit per channel up to 1920 × 1080p at 50/60 Hz. The TDA19995HL supports DVI/HDMI streams with or without High-bandwidth Digital Content Protection (HDCP 1.3) and all Data Island packets. The TDA19995HL settings are controllable via the I²C-bus
