FUNCTIONAL DESCRIPTION

Standby Function

Output three-state function (CF5011AL

×, CF5011AN×)

When INHN goes LOW, the oscillator output on Q goes high impedance.

Oscillator stop function (CF5011AL

×)

When INHN goes LOW, the oscillator stops.

2. In the case of the CF5011AL

×, oscillator stop function is built-in. When INHN goes LOW, normal output stops. When INHN goes HIGH, normal output

is not resumed until after the oscillator start-up time has elapsed.
