SECTION 1: INTRODUCTION Scope and Organization This document is intended to help the hardware designer understand what is necessary to design for the ADV7511W and maintain the highest levels of performance. The ADV7511W Hardware User's Guide (HUG) provides guidelines to design the schematics and board layout.
Rev.A Overview The ADV7511W is a high speed High Definition Multimedia Interface (HDMI) transmitter that is capable of supporting an input data rate up to 165MHz (1080p @ 60Hz, UXGA @ 60Hz). Careful hardware design (schematics and PCB layout) is recommended to optimize the performance and to ensure HDMI compliance.

PLL Circuit 6.2.5 The phase-locked loop (PLL) generates the TMDS output clock as well as clocks used internally by the ADV7511W to serialize the data. The PLL filters high-frequency jitter components to minimize the output data clock jitter. Consumer Electronic Control (CEC) Unused Inputs 6.3.1...
When transmitting video data across the TMDS interface, it is necessary to have an Hsync, Vsync, and Data Enable (DE) defined for the image. There are three methods for sync input to the ADV7511W. See ▶ Figure 17 for a block diagram of the sync processing capabilities.
0x34 0x17[6:5] generation in the embedded sync decoder section. The ADV7511W will use the signal generated by the EAV and SAV as the DE by default, but a new DE can also be generated. Sync adjustment is also available. ▷ Refer to the ADV7511 Programming Guide for details on how to program the DE and sync generator when embedded syncs are used.

The coefficients will be different for each channel. Also included is an offset value for each row of the matrix and a scaling multiple for all values.
The 4:2:2 to 4:4:4 conversion block can convert 4:2:2 input signals into the 4:4:4 timing format. This is necessary, for instance, if the ADV7511W is set in DVI mode and has 4:2:2 format as its video input. The ADV7511W is also capable of performing 4:4:4 to 4:2:2 conversions.
If the transmitted slave address matches the address of the device (set by the state of the A2 input pin as shown in ▶Table 16), the ADV7511W acknowledges by bringing SDA low on the 9th SCL pulse. If the addresses do not match, the ADV7511W does not acknowledge.
