WebVideo decoders have two distinct clocking sources depending upon whether they are locked or unlocked. When the video PLL is locked to the incoming synchronization signal—horizontal sync for video decoders or the TMDS clock for HDMI—it generates a clock that is locked to the incoming video source. WebOct 8, 2024 · The TMDS clock channel is composed of clock+, clock- and clock shield. TMDS channels are synchronized with reference to the clock channel.
