TUSB1064: DP signal detection & indication

*I went through the D/S but found 1064 has no regs/IO to indicate the DP signal status, so may need your double confirm here.

Hi David, 

thank you for the reply,

Can TDP0604/1204 achieve this? I see there is a input signal detection, seems we can detect the input signal by if the device is in standby mode

Thank you,

Charles

You could use TMDS1204 which has a dedicated SIGDEC_OUT pin. 

SIGDET_OUT. Open drain output asserted low when signal is detected on IN_CLK or IN_D2 when HPD_IN is high. Otherwise signal is de-asserted. When used requires 10k or greater pull-up resistor.

Thanks

David

1. TMDS1204 is an HDMI redriver, but see the datasheet has written, can also be configured as DP redriver use, if it is DP mode, SIGDEC_OUT pin can also be used as a detection pin to determine whether there is video stream through?
2. The MUX and DP redriver functions of TUSB1064 are used in YOGA27 and YOGA9. Is there any chance to implement the video stream detection function on TUSB1064?
3. Is there any other MUX+DP redriver integrated IC that can achieve this function?

Is there any other MUX+DP redriver integrated IC that can achieve this function?

Can replace TUSB1064,also support detection video stream function.
