Sync separation level
The sync separation level is changed according to the ratio of H-sync width to one line. Typical sync separation levels
for each format are as follows.

Expressed as percentages, where 286 mVp-p sync applies to 525/60i and 300 mVp-p sync applies otherwise
The format detection and sync separation performances are changed due to the separation level set by HV-SEP setting
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.
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
period.
(Note) Cross-talk from HD, VD, FB or SYNC-in to Video-outs
The edges of HD/VD/FB-out leaks into video-outs when HD-out, VD-out and/or FB-out is output. If the video-out is not
synchronized with the HD/VD/FB-out, (e.g. desynchronized videos between main- and sub-picture like PinP or Double
window), the edges looks as desynchronized noise. The crosstalk level will be improved when the BANDWIDTH
frequency will be set to higher.
Please use this device under consideration of the cross-talk.
