Analog power supply for PLL (+5V)
Analog ground for PLL
Clamp enable
L: Clamp function is enabled. Set to L when the internal clamp is used.
H: Clamp function is disabled. Set to H when the internal clamp is not used.
Connect to ADIN when clamp circuit is used.
Leave this pin open when clamp circuit is not used.
Comb filter analog input (A/D converter input)
Analog ground for A/D converter
Analog power supply for A/D converter (+5V)
Analog chroma signal output
Analog power supply for D/A converter (+5V)
Analog luminance signal output
Analog ground for D/A converter
D/A converter reference voltage setting. Sets the full-scale value for D/A converter.
Connect to DAVD via a capacitor of approximately 0.1µF.
Connect to DAVS via a capacitor of approximately 0.1µF.
Connect a resistor of 16 times (16R) that of the output resistor "R" of AYO pin.

Test. Normally, leave this pin open.
Digital ground
Digital power supply (+5V)
Digital power supply (+5V)
Digital ground
Test. Normally, leave this pin open.
Test. Normally, fix to Low.
Clock input. Input burst-locked clock. Input fsc when the PLL is used. Input 4fsc
when the PLL is not used.
PLL control.
L: When the PLL is not used. The 4fsc clock input to FIN is supplied internally.
H:When the PLL is used. The 4fsc clock from VCO oscillation output is
supplied internally.
Phase comparison output for the internal PLL. Leave open when the PLL is not
used.
VCO oscillation control voltage input for the internal PLL. Connect to PLVS when
the PLL is not used.
