grammed. When placing an order for the DS1099, it is

it is recommended that the unused output be disabled.

The oscillator outputs are asynchronous. Since the

master oscillator and dividers are free running, even

when both outputs are disabled, the state of the output

when OE becomes active is unknown for up to half an

enabled instantaneously. Likewise, if the output is dis-

abled while outputting the low half of a cycle, the out-

put instantaneously is forced high before the current

cycle is completed.

Application Information

Power-Supply Decoupling

To achieve best results, it is highly recommended that

a decoupling capacitor is used on the IC power-supply

pins. Typical values of decoupling capacitors are

0.01µF and 0.1µF. Use a high-quality, ceramic, sur-

face-mount capacitor, and mount it as close as possi-

inductance.
