Pin Name
Cr, R or C input pin.
Input the signal via a capacitor.
Cr, R or CVBS input pin.
Input the signal via a capacitor.
The clamp system is changed according to
CbCr PIN3 or 4 registers.
Audio input pin.
Input the signal via a resistor and a
capacitor. When the resistor value is 5.6 k ,
the internal gain becomes 0 dB (typ.).
Audio or DC voltage input pin.
The input type is changed by AU8 PIN, AU9
PIN or AU10 PIN.
In the case of use as audio input, input the
signal via a resistor and a capacitor. When
the resistor value is 5.6 k , the internal gain
becomes 0 dB (typ.).
In the case of use as DC voltage input, input
the signal via a resistor for protection.
FB (Fast Blanking) signal or DC voltage
input pin.
Connect a resistor between this pin and
GND.
In the case of use as DC voltage input, input
the signal via a resistor for protection.
DC voltage input.
Input the signal via a resistor for protection
purposes.
This pin is also used as a test signal output
pin for shipping only.
