Table 1. Output video formats supported by the IT6604
Notes:
1. Table cells that are left blanks are those format combinations that are not supported by the IT6604.
2. Output channel number is defined by the way the three color components (either R, G & B or Y, Cb & Cr) are
arranged. Refer to Video Data Bus Mappings for better understanding.
3. Embedded sync signals are defined by CCIR-656 standard, using SAV/EAV sequences of FF, 00, 00, XY.
4. The lowest TMDS clock frequency specified by the HDMI standard is 25MHz for 640X480@60Hz.
Supported 3D Formats
The IT6604 supports all the HDMI 1.4a 3D mandatory formats and most optional 3D formats including
♦ [email protected]/24/30Hz -- Framing Packing
♦ [email protected]/24/30Hz -- Top-and-Bottom
♦ 1920x1080i @50/59.94/60Hz -- Side-by-Side ( Half )
♦ 1280x 720P@50/59.94/60Hz -- Framing Packing
♦ 1280x 720P@50/59.94/60Hz -- Top-and-Bottom
Audio Clock Recovery and Data Processing
The audio processing block in the HDMI Sink is crucial to the system performance since human
hearing is susceptive to audio imperfection. The IT6604 prides itself in outstanding audio recovery
performances. In addition, the audio clock recovery PLL uses an external crystal reference so as to
provide stable and reliable audio clocks for all audio output formats.
The IT6604 supports all audio formats and interfaces specified by the HDMI Specification v1.3 through
I2S, S/PDIF and optional one-bit audio outputs. The one-bit audio outputs take on the pins used by I2S
outputs, so only one between the two could be activated at a time.
