ITU-R BT.656 Digital Video Interface connection with i.MX6SL

ko-hey — Wed, 28 Oct 2015 06:06:18 GMT

Hi all

I want to confirm a connection of i.MX6SL with LCD.

My customer want to use eLCDIF in ITU-R BT.656 Digital Video Interface.

So we read section 21.4.11 and 21.4.12 in reference manual but can not understand it.

We understand that they need to connect only data and clock.

However, we can't figure out that which pin can we use as a clock signal.

Which pin can we use ?

Hi Ko-hey

it is LSD_RS (CCIR_CLK) as depicted in Table 21-4.

Pin use in DOTCLK Mode and DVI Mode

Hi Igor

Thank you for reply.

In other words, we should use LCD_DOTCLK pin to provide a clock.

Is it correct ?
