SU01538

87LPC760

QUARTZ CRYSTAL OR

CERAMIC RESONATOR

THE OSCILLATOR MUST BE CONFIGURED IN ONE OF

THE FOLLOWING MODES:

– LOW FREQUENCY CRYSTAL

– MEDIUM FREQUENCY CRYSTAL

– HIGH FREQUENCY CRYSTAL

CAPACITOR VALUES MAY BE OPTIMIZED FOR

DIFFERENT OSCILLATOR FREQUENCIES (SEE TEXT)

A SERIES RESISTOR MAY BE REQUIRED IN ORDER TO

LIMIT CRYSTAL DRIVE LEVELS. THIS IS PARTICULARLY

IMPORTANT FOR LOW FREQUENCY CRYSTALS (SEE TEXT).

SU01539

87LPC760

THE OSCILLATOR MUST BE CONFIGURED IN

THE EXTERNAL CLOCK INPUT MODE.

A CLOCK OUTPUT MAY BE OBTAINED ON

THE X2 PIN BY SETTING THE ENCLK BIT IN

THE P2M1 REGISTER.
