DESCRIPTION
●The TMDS141 HDMI hider is 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. Each TMDS141 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 device includes four TMDS compliant differential receivers with 50-Ω termination resistors and 3.3-V termination voltage integrated at each receiver input pin. External terminations are not required. A built-in frequency response equalization circuit, 8 dB at 825 MHz, compensates inter-symbol interference (ISI) losses from a 5-m or longer input cable link.
