Abstract

Texas Instruments TMDS Clock Detection Solution in HDMI® Sink Applications TS3USB3031, SN65LVDS4, SN65LVDS17, application note presented a method for High-Definition Multimedia Interface (HDMI®) sink applications such as digital TVs, monitors, and other display equipment to wake up from standby or sleep mode by detecting Transition-Minimized Differential Signaling (TMDS) clock in HDMI applications. But with the latest HDMI2.1 Fixed Rate Link, with the TMDS clock lane being re-purposed as FRL data lane, a new detection method is needed.
