Function Description
Standby Function
When INHN goes LOW, the oscillator stops and the output on Q becomes high impedance.

Normal Operation
Power-saving Pull-up Resistor
The INHN pin pull-up resistance RUP1 or RUP2 changes in response to the input level(HIGH or LOW). When INHN is tied
LOW level, the pull-up resistance is large(RUP1),reducing the current consumed by the resistance. When INHN is left open
circuit, the pull-up resistance is small(RUP2),which increases the input susceptibility to external noise. However, the pull-up
resistance ties the INHN pin HIGH level to prevent external noise from unexpectedly stopping the output.
Oscillation Detector Function
The XO5028 series also feature an oscillation detector circuit. This circuit functions make the outputs disable until the oscillator
circuit starts and oscillation becomes stable. This alleviates the danger of abnormal oscillator output at oscillator start-up when
power is applied or when INHN is switched
