ADV202
VIDEO INPUT FORMATS
The ADV202 supports a wide variety of formats for
uncompressed video and still image data. The actual interface
and bus modes selected for transferring uncompressed data
dictates the allowed size of the input data and the number of
samples transferred with each access.
The host interface can support 8-, 10-, 12-, 14-, and 16-bit data
formats. The video interface can support video data or still image
data input/output. Supported formats are 8-, 10-, 12-, or 16-bit

Input rate limits for HDATA can be less for certain applications depending on input picture size and content, host interface settings, and DMA transfer settings. Values
in brackets refer to the 135 MHz speed grade version of the ADV202.
Minimum guaranteed sustained output rate or minimum sustainable compression rate (input rate/minimum peak output rate).
Maximum peak output rate, or output rate above this value is not possible .

than provided by specifying the actual data width/precision in
the PMODE register.
The maximum allowable data input rate is limited by using
irreversible or reversible compression modes and the data width
(or precision) of the input samples. Use Table 24 and Table 25 to
determine the maximum data input rate.
