TFP410: Time specification from input to output

Yuichiro Kimura

Part Number: TFP410

Hello, Support team

When the TFP 410 is powered on and the PD pin is changed from LOW to HIGH,
Is there a limitation on the time from the input of the RGB signal to the output of the TMDS signal?

Please also let me know about the following.

> When the PD pin is changed from LOW to HIGH after turning on the power,
how long is the time for the device to become active?
> How long is the time between the internal PLL is locked and active?

Hello Sopatopa,
On power-up it typically can take anywhere from 30-50us to output data, this time is dependent on the power supply ramp. Once the device is powered, the delay from input to TMDS encoded output is 1 clock cycle for all data/ctl inputs.
