We are planning to use ADV7513 HDMI Transmitter in our design. Can you please tell regarding Output HDMI Cable length supported by the device? I was not able to find it in the datasheet of ADV7513.
HDMI cable lengths are not defined in the ADV7513 data sheet or the HDMI specifications. The HDMI specifications only define an expected impedance.
In practical terms, it really depends on the quality of the cable. We've seen some very short cables which don't work at 1080p while we also seen 7 meter cables that work fine at 1080p. Normal cables are 2 meters.
Also cable problems are more prevalent at 1080p due to the higher clock rates. 720p formats are generally more tolerant of cable quality.
