TFP401: Hot Plug capability

Koshi Ninomiya

Part Number: TFP401

Hi Team,

My customer is checking the datasheet of TFP401 and there are some questions from them.

Q1: Does the TFP401 support hot plug?
Is it okay if a valid video signal (clock, data) is input (with an HDMI cable connected) after the device is powered on?

Q2: The data corresponding to following "TCLKPD" in Figure 11. Output Signals Disabled Timing from Clock Inactive, and "TCLKPU+TFSC" in Figure 12. Wake-Up on Clock Detect in datasheet page 16 of SiI1161 (Silicon Image) could not be read from the datasheet of TFP401.
What is the value corresponding to "TCLKPD" in the TFP401?
What is the value corresponding to ""TCLKPU+TFSC" in the TFP401?

Hi Ninomiya-san,

Q1: Yes, this is fine.

Q2: This is not applicable to the TFP401 as it does not have a clock detect feature. Please see the "Sync Detect" section of the datasheet.

I.K.

Hi I.K.-san,

About Q2:
Is there any information about how long it takes from the input of clock and data (=hot plug) to the output of valid clock and data from the TFP401 after the device power is turned on?
Information such as tens ms, a few ms, hundreds us, tens us, and a few us orders may be used instead of detailed values.
Thank you.

Best Regards,

Hi Koshi-san,

No but I will see if I can take a measurement next time I'm in the lab early next week.

Hi Koshi-san,

I'm not able to get an accurate measurement since the scope can't capture the full time, but it looks to be hundreds of us.
