We are interested in converting 1080p30 Component HD (YPbPr) analog video to HD-SDI. I wanted to know if the AD9984A supports the 1080p30 Component HD video standard and if the parallel outputs from the AD9984A would be compatible with the GV7700.
the 1080p30 is being outputted by a Camera device. there would be a microcontroller to initialize the two chips
Hi Poornima,
Thank you for your reply.
at 1080p30 what would the Parallel/Pixel Output Clock be for theAD9984A? in Table10 of the datasheet i don't see a line for 1080p30 ?
GV7700 is expecting the data in YCbCr format so i believe the AD9984A should support it.
the GV7700 can receive parallel data in either 20-bit demultiplexed or 10bit multiplexed. In 10bit multiplexed mode the max PCLOCK is 148.5Mhz and in 20bit demultiplexed its 74.25Mhz
from the GV7700 datasheet
Hi
As long as the pixel clock of particular resolution should not exceed the 170MHZ (i.e Maximum clock supported by AD9984A), It can support all HDTV video modes up to 1080p60/1080p30 .
If table 10 does not list the formats in that case select the format close to the one based on pixel rate and tweak from there using register configuration.
