CIRCUIT DESCRIPTION
I/O
I Mute control pin.
I Composite Y signal input.
- Ground pin.
I Composite Cb signal input.
- Unused.
I Composite Cr signal input.
O Output of the composite Cr signal.
O Output of the composite Cr signal.
O Output of the composite Cb signal.
O Output of the composite Cb signal.
O Output of the composite Y signal.
O Output of the composite Y signal.
- Power supply pin.
I/O
I Crystal resonator connection.
I Chip enable.
I Input serial data.
Used as the synchronization clock when serial data is input to the DI(pin 3), or
I
when serial data is output DO(pin 5).
O Outputs serial data.
• Dedicated output pins.
• The output states are determined by B01 to B04 in the serial data.
O
"Data" =0 : Open "Data" =1 : Low
• These pins go to the open state after the power-on reset.
Pins used for both input and output.
I/O The input or output state is determined by bits I0C1and I0C2 in the serial data.
"Data" = 0 : Open, "Data" = 1: Low
I IF count input.
I Local oscillator signal input.
I Local oscillator signal input.
- Power supply.
O PLL charge pump output.
I
The MOS transistor used for the PLL active low-pass filter.
O
- Ground.
O Crystal resonator connection.
