DS90C385A: DS90C385A - Inquiry about 'How to RGB666 interface connection'

Jinuk Yoon

Part Number: DS90C385A

Tool/software:

I'm trying to drive an LCD using an RGB666 (16-bit input) source, connecting only TxOUT0 to TxOUT2.

To achieve this, I'd like to inquire about how to connect the pinmap interfaces for the inputs(TxIN0 to TxIN27). [connection order, MSB, LSB connection rules, etc.]

The datasheet doesn't provide any specific connection examples or methods, so I'm wondering how to connect them.

Thanks!

Hi Jinuk,

Do you have the panel datasheet showing how the bits in the LVDS frame are mapped? There are similar E2E threads (link below) showing how to map from parallel RGB to LVDS if you have not searched there already.

Best,

Jack

Thank you for your kind reply.

Should I connect the input source and C385 as shown in the table above?

For the pins that are not connected (TxIN5, TxIN10, TxIN11, TxIN16, TxIN17, TxIN27) should I 'FLOAT' or do something like 'GND' connection?

I look forward to hearing from you once again.

Thanks!
