8. OPERATING PRECAUTIONS
8.1
(1) Resistors
(2) Capacitors
(3) Crystal resonators
(4) Ceramic resonators
Use E24 series resistors (approximately 5% precision) of 1/4 W or higher.
• Ceramic capacitors of 1000 pF or below
• Ceramic capacitors of 1000 pF or higher
• Electrolytic capacitors
Use crystal resonators of 16 pF load type as shown below.
• For PAL
• For NTSC : 3.579 545 MHz (model name: TQC203A-8R (HC-49/U-10 type), manufactured by Toyo
Note that use of crystal resonators other than the above may deteriorate electrical characteristics.
Use ceramic resonators as shown below.
• CSB500 F23 (manufactured by Murata Mfg. Co., Ltd.)
Note that use of ceramic resonators other than the above may deteriorate mainly electrical characteristics of the sync.

PC1830 External Components
Capacitors used for the time constant circuit. Basically use E12 series (10% precision) ones with the center value
= 0 in nominal temperature characteristic.
Equivalent to capacitors for non-critical time constant circuits and for clamp, and bypass capacitors between power
supply and GND. Use E12 series (10% precision) ones. Use a type whose capacitance is not extremely affected
by temperature variations (ie. with an excellent temperature characteristic).
Use E6 series (20% precision) ones. Use ones whose capacitance is not extremely affected by temperature
variations (ie. with an excellent temperature characteristic).
