TMDS141RHAR (TEXAS INSTRUMENTS)

The TMDS141RHAR is a HDMI Hider designed to accommodate a 1m 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. Each TMDS141 contains four TMDS repeaters to transmit digital content with signaling rates of up to 2.25Gbps and an I?C repeater to link extended display identification data (EDID) reading and high-bandwidth digital content protection (HDCP) key exchange under I?C standard mode operations. The device includes four TMDS compliant differential receivers with 50R termination resistors and 3.3V termination voltage integrated at each receiver input pin. External terminations are not required. A built-in frequency response equalization circuit, 8dB at 825MHz, compensates inter-symbol interference (ISI) losses from a 5m or longer input cable link. The device also includes four TMDS compliant differential drivers.
