Description

The TDP158 device is an AC-coupled HDMI signal to transition-minimized differential signal (TMDS) Redriver supporting digital video interface (DVI) 1.0 and high-definition multimedia interface (HDMI) 1.4b and 2.0b output signals. The TDP158 supports four TMDS channels and Digital Display Control (DDC) interfaces. The TDP158 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 TDP158 can be configured to support the HDMI 2.0 standard.

The TDP158 supports dual power supply rails of 1.1 V on VDD and 3.3 V on VCC for power reduction. Several methods of power management are implemented to reduce overall power consumption. TDP158 supports fixed receiver EQ gain using I2C or pin strap to compensate for different lengths input cable or board traces.
