4 Summary

With the usage of TMDS1204 SIGDET_OUT pin, this presents a simpler clock and signal detection circuitry implementation design for HDMI1.4, 2.0, and 2.1. The HDMI/FRL source can determine HDMI/FRL sink receiver termination and transmit clock and signal when the user activates the source from the standby mode, and eventually the HDMI/FRL sink can detect TMDS clock or FRL signal running and wake up the system without any control.
