The bypass capacitor of Vcc is arranged near the LogicGND pin.
In order to mitigate the surroundings lump by the VIF input, the balanced connection from a SAW filter to
the VIF input pin of 37.38 recommends a putter which serves as a 1t coil by Tip C or the jumper.
In order to stop digital beat which goes via the port output from Logic Vcc, bypass capacitor arranged near
the port output pin.
It is high impedance. keep away from VideodetOUT and EQ F/B pin.

Notes about the handling of IC
*20
The direct power supply impression to Vt terminal is forbidden. When power supply impression is required,
please impress through the resistance for current restrictions. Depending on the case, it is drive current from
31 pin, and excessive collector current flows and breaks to an external transistor.
Because there is a possibility of also destroying IC by the destruction.
Since this IC is using the detailed process, be careful of serge enough.
Especially careful 1,7,8,9,10,25,26,27,32,48 pins.
