DS1099
Low-Frequency Dual EconOscillator
General Description
The DS1099 is a low-cost, low-power, low-frequency
silicon oscillator that generates two square-wave out-
puts with frequencies between 0.25Hz and 1.048MHz.
Individual output enables allow both outputs to be
enabled/disabled independently. Both outputs are
capable of sinking 16mA, allowing them to directly
interface to light-emitting diodes (LEDs) as well as other
external circuitry. The DS1099 operates over a wide
supply voltage, making it suitable for both 3V and 5V
systems. The device is shipped from the factory custom
programmed and calibrated, ready to be inserted into
the end application.
Contact the factory for custom frequencies or require-
ments.

Note 1:All voltages referenced to ground.
Note 2:Active supply current combines the standby current with the output current. The output current is defined by
I = (CLOAD+ 12pF ) x VCCx fOUTfor each output when enabled.
Note 3:This is the change observed in output frequency due to changes in temperature or voltage.
Note 4:This parameter is guaranteed by design.
Note 5:This indicates the time between power-up and the outputs becoming active.

Low-Frequency Dual EconOscillator
Detailed Description
The DS1099 consists of a fixed-frequency 1.048MHz
master oscillator followed by two independent factory-
programmable dividers. The two divider outputs are
connected to pins OUT0 and OUT1, which are inde-
pendently enabled/disabled using the output-enable
pins, OE0and OE1, respectively. When the output-
enable pins are active (low), the corresponding outputs
are enabled. If either output-enable pin is tied to its
inactive state (high), then the corresponding output is
disabled and forced high immediately. The output-
enable pins only disable the corresponding output
driver(s) and do not shut down the master oscillator or
the dividers.
Since the master oscillator frequency, fMOSC, is fixed,
the frequency of OUT0 and OUT1 is determined by
DIVIDER 0 and DIVIDER 1, respectively. And since
each output has its own divider, fOUT0and fOUT1can
be programmed independent of each other.
The frequency of the outputs are calculated as follows:
fOUT0= fMOSC/ 2X0= 1.048MHz / 2X0
fOUT1= fMOSC/ 2X1= 1.048MHz / 2X1
where X0is the DIVIDER 0 setting and X1is the
DIVIDER 1 setting. Valid values for X0and X1are inte-
gers 0 to 22 (dec).
Table1 shows output frequencies and divider values
for the range of divider settings.

Maxim cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim product. No circuit patent licenses are
implied. Maxim reserves the right to change the circuitry and specifications without notice at any time.
The divider settings, X0and X1, are factory pro-
grammed. When placing an order for the DS1099, it is
required to specify X0and X1. 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 OEbecomes active is unknown for up to half an
fOUTperiod. When OEis 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 VCCand GND pins of the IC to minimize lead
inductance.
