13.3.7 HSYNCO Output
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 external
circuitry. The meaning of the HSYNCO output in each mode is shown in table 13.9.
Table 13.9 Meaning of HSYNCO Output in Each Mode
Mode IHI Signal IHO Signal Meaning of IHO Signal
No signal HFBACKI
input
IHI signal (without
2fH modification)
HFBACKI input is output directly
IHI signal (with 2fH
modification)
Meaningless unless there is a double-frequency
part in the HFBACKI input
CL1 signal HFBACKI input 1 interval is changed before output
IHG signal Internal synchronization signal is output
S-on-G
mode
CSYNCI
input
IHI signal (without
2fH modification)
CSYNCI input (composite synchronization signal)
is output directly
IHI signal (with 2fH
modification)
Double-frequency part of CSYNCI input (composite
synchronization signal) is eliminated before output
CL1 signal CSYNCI input (composite synchronization signal)
horizontal synchronization signal part is separated
before output
IHG signal Internal synchronization signal is output
Composite

HSYNCI
input
IHI signal (without

HSYNCI input (composite synchronization signal)
is output directly
IHI signal (with 2fH

Double-frequency part of HSYNCI input (composite
synchronization signal) is eliminated before output
CL1 signal HSYNCI input (composite synchronization signal)
horizontal synchronization signal part is separated
before output
IHG signal Internal synchronization signal is output
