It allows up to three DVI or HDMI source ports to be switched to a single display terminal with four TMDS channels per port supporting signaling rates up to 3 Gbps for 1080p resolution in 16-bit color depth. The integrated adaptive equalizer automatically compensates for intersymbol interference (ISI) loss of up to 20 dB at 3 Gbps, supporting cable lengths up to 20 meters. The device includes a DDC repeater, TMDS clock-detect circuit for automatic power management, and enhanced ESD protection rated at 10 kV HBM on all source-side pins.","working_principle":"The TMDS361B operates as a 3:1 multiplexer on the sink side of an HDMI\/DVI link. When an input port is selected via I2C or GPIO control, the integrated 50-ohm termination resistors on the TMDS clock channel are activated, the clock-detect circuit is enabled, and the DDC repeater is engaged. Upon detecting a valid TMDS clock, the data-line terminations are enabled and the TMDS outputs are activated. The adaptive equalizer on each input automatically adjusts its gain profile to compensate for the frequency-dependent loss of the connected cable, restoring signal integrity before the signal is re-driven to the display. When a port is not selected, terminations are disconnected, receivers are disabled, and the DDC repeater is turned off to minimize power consumption.","pin_description":"
