The divider settings, X
0
and X
1
, are factory pro-
grammed. When placing an order for the DS1099, it is
required to specify X
0
and X
1
. If only one output is used,
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
f
OUT
period. When OE is brought low, the output is
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-
ble to the V
CC
and GND pins of the IC to minimize lead
inductance.
