With the HSYNCO output, the meaning of the signal source to be selected and use or non-use of
modification varies according to the IHI signal source and the waveform required by an external
circuitry. The HSYNCO output modes are shown in table 13.11.

Meaning of IHO Signal
HFBACKI input is output directly
Meaningless unless there is a double-frequency
part in the HFBACKI input
1 interval of HFBACKI input is changed before
output
Internal synchronization signal is output
CSYNCI input (composite synchronization
signal) is output directly
Double-frequency part of CSYNCI input
(composite synchronization signal) is eliminated
before output
Horizontal synchronization signal part of
CSYNCI input (composite synchronization
signal) is separated before output
Internal synchronization signal is output
HSYNCI input (composite synchronization
signal) is output directly
Double-frequency part of HSYNCI input
(composite synchronization signal) is eliminated
before output
Horizontal synchronization signal part of
HSYNCI input (composite synchronization
signal) is separated before output
Internal synchronization signal is output
HSYNCI input (horizontal synchronization signal)
is output directly
Meaningless unless there is a double-frequency
part in the HSYNCI input (horizontal
synchronization signal)
1 interval of HSYNCI input (horizontal
synchronization signal) is changed before output
Internal synchronization signal is output
