Cautions for Use
1. Drive capacity of video driver
Line outputs can drive two systems through capacitive coupling.
Component outputs can drive one systems through capacitive coupling.
Scart output can drive one system only through DC coupling.
2. Audio Mute
This IC incorporates a mute transistor to reduce the POP noise of audio output when power is turned ON/OFF.
Mute control can be made by serial control.
3. Resistor to limit the Audio input
When the large signal is input in the input pin with power OFF, cross-talke between input and output occurs through the
protective diode and parasitic elements. Because of the structure of LSI, such cross-talke is difficult to avoid.
If cross-talk at a time of power OFF presents a problem, the cross-talk amount can be reduced by inserting the limiting
resistor in the input.
In this case, the input signal level changes depending on the resistance value. Determine the constant while taking both
the cross-talk amount and input level into account.
4. Pin treatment when external control is not to be used
When external control pins (Pins 26) are not used, pull-down to GND is recommended.
5. Audio 9V_REG pin external capacitance
Use the Audio 9V_REG pins (pins 52 and 57) external capacitance of 10μF or more and with the equivalent series
resistance component of 7Ω or less.
6. Power application and disconnection sequences
The recommended power application sequence to this IC is VCC_ALL5V (Pin28) → VCC5V (Pins 5, 9, 13, 24, 30 and
43), VCC12V (Pin29).
(No particular order is established between VCC5V and VCC12V.) It is recommended to reverse the above sequence
when power supply is turned OFF.
