ADV8003 Hardware Manual
Rev. B, August 2013 16
The ADV8003 supports all common consumer formats as outlined in the EIA-861 specification and many common professional output
formats as outlined in the VESA specification.
The part supports the I2C® and SPI protocols for communication with the system microcontroller.
Note:
There are seven options within the ADV8003 family of parts, each with different capabilities but all in the same CSPBGA-425
package. These are described in Table 1 .

Note that ADV8003KBCZ-8/7 functionality is described throughout this manual (figures, functional blocks, and so on). Some sections of
this manual are not relevant to the ADV8003KBCZ-8B/7B, ADV8003KBCZ-8C/7C and ADV8003KBCZ-7T as they do not include those
blocks. If a section is not relevant to a particular generic, this is indicated in the introduction to that section.
1.1.1. Digital Video Input
Video data can be input into the ADV8003 in a number of ways. The flexible 60-bit TTL input port can be configured for dual video
inputs (video TTL input and EXOSD TTL input), for a single video input (interleaved TTL data from an ADV7619 ) or for a single video
input and an external alpha channel. The 60-bit TTL input port is extremely flexible and can be configured into a number of different
arrangements; for more information, refer to
Table 95 and Table 96 . Video can also be input into the ADV8003 via the Serial Video Rx
which can be used for device to device interconnect, for example, a serial video link between the ADV7850 and the ADV8003 or a serial
video link between the ADV7623 and the ADV8003. Using such front end devices located before the ADV8003 allows the audio to be
extracted and processed in a DSP before being reinserted into the ADV8003.
A mux after the TTL inputs allows the video TTL input pins and the EXOSD TTL input pins to be connected to either the primary or the
secondary input channel. The primary input channel features an input formatter, manually programmable CSC, updither function, ACE,
contrast, brightness and saturation controls. The secondary input channel features an input formatter, manually programmable CSC and
updither function. The Serial Video Rx is connected directly to the Rx input channel and features an input formatter, manually
programmable CSC and updither function.
