Analog Devices Advantiv ADV7604 Hardware Manual page 126

Notes:
• The horizontal measurements are valid only if
• The HDMI DE/HSync filter is used solely to measure the horizontal synchronization signals
decoded from the HDMI stream. The HDMI DE/HSync filter is not in the main path of the
synchronization processed by the part and does not delay the overall HDMI data into video
data out latency.
• The unit for horizontal filter measurement is a pixel that is the actual element of the picture
content encapsulated in the HDMI/DVI stream which the ADV7604 processes. A pixel has a
