NOTES

1Temperature ranges: B Version –40

°C to +85°C: Y Version: –40°C to +105°C.

2See Terminology.

3Guaranteed by design and characterization, not production tested.

4Span = Maximum Output Frequency–Minimum Output Frequency.

5The absolute voltage on the input pin must not go more positive than V

DD – 2.25 V or more negative than GND.

6Because this pin is bidirectional, any external reference must be capable of sinking/sourcing 400

µA in order to overdrive the internal reference.

7These logic levels apply to CLKOUT only when it is loaded with one CMOS load.

Specifications subject to change without notice.
