Product Summary
The TMDS141RHAR is a HDMI hider designed to accommodate a 1-m HDMI cable between a HDMI connector and a receiver. The internal cable causes signal distortion to high-speed TMDS signals, as well as increasing capacitance to the DDC channel. The TMDS141RHAR contains four TMDS repeaters to transmit digital content with signaling rates of up to 2.25-Gbps, and an I2C repeater to link extended display identification data (EDID) reading and high-bandwidth digital content protection (HDCP) key exchange under I2C standard mode operations. The applications of the TMDS141RHAR include Digital TV, DVD Player, Set-Top-Box, Audio Video Receiver, Digital Projector, DVI or HDMI cable.
