The recommended operating frequency is a yardstick value derived from the crystal used for PTI 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.

The Q output becomes high impedance and the oscillator circuit stops. OE Q Oscillator HIGH(or open) f0 output frequency Normal operation LOW High impedance Stopped Build-in voltage regulator The voltage regulator generate a stable voltage supplying the oscillator, significantly reducing current consumption and crystal current, significantly reducing the oscillator characteristics supply voltage dependency. Power-saving Pull-up Resistor The INHN pin pull-up resistance changes in response to the input level(HIGH or LOW).When OE is tied LOW ,the pull-up resistance becomes large, reducing the current consumed by the resistance. When INHN is left open, pull-up resistance becomes small, such that even if the input is affected by external noise the outputs are stable due to INHN being tied HIGH by the pull-up resistor. Oscillation Detector Function The devices also feature an oscillation detector circuit. This circuit function to disable the outputs until the oscillator circuit starts. This prevents abnormal oscillator output at oscillator start-up when power is applied or when INHN is switched. PT0310(09/08) 2 Ver:1
