VSYNCO Output
With the VSYNCO output, the meaning of the signal source to be selected and use or non-use of
modification varies according to the IVI signal source and the waveform required by external
circuitry. The VSYNCO output modes are shown in table 14.11.

Meaning of IVO Signal
VFBACKI input is output directly
Meaningless unless VFBACKI input is
synchronized with HFBACKI input
VFBACKI input fall is modified before output
VFBACKI input fall is modified and signal is
synchronized with HFBACKI input before
output
Internal synchronization signal is output
CSYNCI/HSYNCI input (composite
synchronization signal) vertical
synchronization signal part is separated
before output
CSYNCI/HSYNCI input (composite
synchronization signal) vertical
synchronization signal part is separated, and
signal is synchronized with CSYNCI/HSYNCI
input before output
CSYNCI/HSYNCI input (composite
synchronization signal) vertical
synchronization signal part is separated, and
fall is modified before output
CSYNCI/HSYNCI input (composite
synchronization signal) vertical
synchronization signal part is separated, fall is
modified, and signal is synchronized with
CSYNCI/HSYNCI input before output
Internal synchronization signal is output
