PIXEL INPUT/OUTPUT FORMATTING

The output section of the ADV7619 is highly flexible. The pixel

output bus can support up to 36-bit 4:4:4 YCrCb or 36-bit 4:4:4

RGB. For resolutions higher than 1080p, the pixel output bus

supports two 24-bit 4:4:4 RGB/YCrCb.

Part supports SDR (single data rate) and double data rate

(DDR) outputs. SDR is supported up to 170 MHz LLC

frequency (UXGA, 1080p60 for any OP_FORMAT_SEL or

up to 300 MHz HDMI signals output on two 24-bit parallel

video sub buses OP_FORMAT_SEL = 0x94, 0x95, 0x96, or

0x54; refer to Table 12). DDR can be supported with LLC clock

frequency up to 50 MHz (video modes with original pixel clock

lower than 100 MHz, such as 1080i60). In SDR mode, 16-/20-/

24-bit 4:2:2 or 24-/30-/36-bit 4:4:4 output is possible. In DDR

mode, the pixel output port can be configured for 4:2:2 YCrCb

or 4:4:4 RGB for data rates up to 27 MHz.

Bus rotation is supported.

Table 7 through Table 12 provide the different output formats

that are supported. All output modes are controlled via I2C.

For resolutions higher than 1080p, the video signals are routed

directly to the pixel bus output as two 24-bit (4:4:4) buses running

at up to 150 MHz. In this mode, the output data format is the

same as the input format.

PIXEL DATA OUTPUT MODE FEATURES

For resolutions up to 1080p Deep Color, the output pixel port

features include the following:

•

SDR 8-/10-/12-bit ITU-R BT.656 4:2:2 YCrCb with embed-

ded time codes and/or HS, VS, and FIELD output signals

•

SDR 16-/20-/24-bit 4:2:2 YCrCb with embedded time codes

and/or HS and VS/FIELD pin timing

•

SDR 24-/30-/36-bit 4:4:4 YCrCb/RGB with embedded time

codes and/or HS and VS/FIELD pin timing

•

DDR 8-/10-/12-bit 4:2:2 YCrCb for data rates up to 27 MHz

•

DDR 12-/24-/30-/36-bit 4:4:4 RGB for data rates up to

27 MHz

For resolutions greater than 1080p Deep Color (direct pass-

through of video signal), the output pixel port features include

the following:

•

8-bit 4:4:4 RGB/YCrCb for resolutions up to 2160p

•

12-bit 4:2:2 RGB/YCrCb for resolutions up to 2160p
