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 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 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.
● Supports 2.25Gbps signalling rate for up to 1080p resolutions
● Supporting 36-bits per pixel for colour depth of 12-bits per colour
● Compatible with HDMI 1.3a
● Integrated receiver termination
● 8dB Equalizer compensates losses from 5m or longer HDMI cables
● Selectable output de-emphasis supports 1m HDMI transmission
● I²C Repeater isolates BUS capacitance at both ends
● High impedance outputs when disabled
● TMDS inputs hBM ESD protection exceeds 6kV
● Green product and no Sb/Br
●Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
