Sync separation level

and the connected coupling capacitor value. The careful evaluations are required to set the separation level under
consideration of expected input conditions such as a suppressed sync input, an input with V-sag, and APL (Average
Picture Level) fluctuations.
period.
The sync separation level is changed according to the ratio of H-sync width to one line. Typical sync separation levels
The format detection and sync separation performances are changed due to the separation level set by HV-SEP setting
For “Sync on G” signal, HD-OUT is not output during the V-sync period because there is no H-sync during the V-sync
Expressed as percentages, where 286 mVp-p sync applies to 525/60i and 300 mVp-p sync applies otherwise
