µPC1862

Recommended pattern

The

µPC1862 generates system clock for synchronous signal processing and clock generate processing.

If the supply voltage, line placement and routing are not set appropriately that the

µPC1862 cannot generate correct

system clock.

Though the recommended pattern is not shows in this document, note points shown below at designing.

1.

For synchronous section and chroma section, each power supply must be isolated.

2.

Lines to pin 9 to pin 13 should be as thick and short as possible.

3.

Connect resonator as near IC as possible. Don’t put GND line between resonator pins for parasitism capacitance.
