Other Parts Discussed in Thread: TMDS361B, TMDS361, HD3SS215

Hi Team,

Customer used TMDS361B before. Now customer is requesting 4K 1:3 switch.

Also, customer also need to the clock detection function as TMDS361. (SOC can read back TMDS361 I2C register’s value)

Would you please recommend the proper solution for this?

We currently do not have a 1:3 MUX that supports HDMI4K. The customer can use HD3SS215 and cascading two of them together.

Thanks

Hi David,

thanks for feedback

Is there any way for scalar to know there is clk on the HDMI port in order to wake up the monitor from power saving mode?

TMDS361 has I2C to indicate the HDMI's clock event.
