Chip form devices have designation CF5005A××. 2. 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. 3.

SEIKO NPC CORPORATION —6 SM5005A series FUNCTIONAL DESCRIPTION Standby Function The oscillator stops when INHN goes LOW. When the oscillator stops, the oscillator output on Q goes high impedance. INHN Q Oscillator HIGH (or open) fO output frequency Normal operation LOW High impedance Stopped Power-saving Pull-up Resistor 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.
