Differential and Complimentary outputs enabled.
CONNECTION
Both outputs are disabled (high impedance) when
Control Pad is taken below 0.45*Vcc referenced to
Ground (threshold). Oscillator is always ON. Only
the buffer stage is disabled.
DISABLE
F
* Custom frequency stability is available; e.g. for +/-20 ppm over
-10 to +60°C use 'C' for custom, I.e. C20.
Both outputs are enabled when Control Pad is
taken above 0.45*Vcc referenced to Ground
(threshold). Enable time 10ns +1 period of output
