ADV7619 interleaved Mode 0 to support less than 170Mhz

Hi,

   on ADV7619 hardwae guide, there says:

"PIXEL PORT CONFIGURATION

The ADV7619 hasa very flexible pixel port, which can be configured in a variety of formats to accommodate downstream ICs. The ADV7619 can provide output modes up to 36 bits or video with pixel clock frequency below 170 MHz, and 48 bits for video with pixel rates above 170 MHz.

For an HDMI stream with bit pixel rates above 170 MHz, ADV7619 outputs data using two video buses running at half the video pixel clock frequency. Video data is interleaved. On a single clock edge, the first bus outputs information about odd pixels and the second video bus outputs information about even pixels. Video output modes for pixel rates above 170 MHz are shown in Table 83."

 

My question is, if can I use the same interleave pixel output mode to support all resolution?  (including >170Mhz, such as 4K*2K; and <170Mhz, such as 1080P, 720P);  OP_FORMAT_SEL[7:0] set to 0x54, 0x94, 0x95, 0x96 modes;

it is helpful for the back-end FPGA design; have we tested it on our EVAL system?

 

Thanks & Best Regards!
