I've an application where I need to send either RGB 8:8:8 or YCbCr 4:2:2 formatted data through a serial link.
I chose DS90UH925AQ because it supports enough input lanes for both types of data + HS, VS, DE, and PCLK
Our video source is NOT an HDCP compliant source ... in fact, it is just a CMOS camera that outputs parallel LVCMOS data in either RGB 8:8:8 or YCbCr 4:2:2 @ 27MHz pixel clock
As I understand it from the datasheet, the HDCP cipher functionality of the DS90UH925AQ serializer and DS90UH926Q deserializer occurs only between this chipset ... not the external world. The HDCP cipher action is transparent to the application. So my conclusion is that serializing & deserializing using a video source that does not know or care about HDCP should still function correctly using this chipset. Is my conclusion here accurate & correct?
Also: YCbCr 4:2:2 requires 16-bit packets for each clock, leaving 8 bits unconnected to the serializer input. If I connect all G[7:0] inputs to ground, will the SER/DES functionality be maintained in this transmission mode?
