DS1099
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, OE0 and 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, fOUT0 and fOUT1 can
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 X0 is the DIVIDER 0 setting and X1 is the
DIVIDER 1 setting. Valid values for X0 and X1 are inte-
gers 0 to 22 (dec).
Table 1 shows output frequencies and divider values
for the range of divider settings.
