The recommended operating frequency is a yardstick value derived from the crystal used for NPC characteristics authentication. However, the oscillator frequency band is not guaranteed. Specifically, the characteristics can vary greatly due to crystal characteristics and mounting conditions, so the oscillation characteristics of components must be carefully evaluated.

NIPPON PRECISION CIRCUITS INC.—6 CF5014 series FUNCTIONAL DESCRIPTION Standby Function When INHN goes LOW, the oscillator stops and the oscillator output on Q becomes high impedance. INHN Q Oscillator HIGH (or open) Any fO, fO/2, fO/4, fO/8 or fO/16 output frequency Normal operation LOW High impedance Stopped Power-save Pull-up Resistance The INHN pull-up resistance changes in response to the input level (HIGH or LOW). When INHN goes LOW (standby state), the pull-up resistance becomes large to reduce the current consumption during standby.
