13.3.8 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 meaning of the VSYNCO output in each mode is shown in table 13.10.
Table 13.10 Meaning of VSYNCO Output in Each Mode
Mode IVI Signal IVO Signal Meaning of IVO Signal
No signal VFBACKI
input
IVI signal (without fall
modification or IHI
synchronization)
VFBACKI input is output directly
IVI signal (without fall
modification, with IHI
synchronization)
Meaningless unless VFBACKI input is
synchronized with HFBACKI input
IVI signal (with fall
modification, without IHI
synchronization)
VFBACKI input fall is modified before output
IVI signal (with fall
modification and IHI
synchronization)
VFBACKI input fall is modified and signal is
synchronized with HFBACKI input before
output
IVG signal Internal synchronization signal is output
S-on-G
mode or
composite
mode
PDC signal IVI signal (without fall
modification or IHI
synchronization)
CSYNCI/HSYNCI input (composite
synchronization signal) vertical
synchronization signal part is separated
before output
IVI signal (without fall
modification, with IHI
synchronization)
CSYNCI/HSYNCI input (composite
synchronization signal) vertical
synchronization signal part is separated, and
signal is synchronized with CSYNCI/HSYNCI
input before output
IVI signal (with fall
modification, without IHI
synchronization)
CSYNCI/HSYNCI input (composite
synchronization signal) vertical
synchronization signal part is separated, and
fall is modified before output
IVI signal (with fall
modification and IHI
synchronization)
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
IVG signal Internal synchronization signal is output
