Notes 1.

CR constant must be satisfied with Power-ON Clear Specification (refer to 6. ELECTRICAL

CHARACTERISTICS).

This circuit can reduce the number of external components and facilitates the adjustment of oscillation

frequency, using LC module (part number: Q285NCIS-11181, manufactured by Toko, Inc.)

Connect these pins as follows when inputting external clock:

OSCIN pin: external clock input, OSCOUT pin: open

Signals in ( ) are set by a mask option (RGB + RGB compatible blanking).

Remarks 1. The number in the parentheses indicates the pin number of the

µPD6461GT-xxx.

2. With the

µPD6461GT-xxx, influence by noise via lead frame can be surpressed by connecting the

N.C. pins (3, 12, 13, 22) to GND.
