Detailed Desc ription
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, f
MOSC
, 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, f
OUT0
and f
OUT1
can
be programmed independent of each other.
The frequency of the outputs are calculated as follows:
f
OUT0
= f
MOSC
/ 2
X0
= 1.048MHz / 2
X0
f
OUT1
= f
MOSC
/ 2
X1
= 1.048MHz / 2
X1
where X
0
is the DIVIDER 0 setting and X
1
is the
DIVIDER 1 setting. Valid values for X
0
and X
1
are inte-
gers 0 to 22 (dec).
Table 1 shows output frequencies and divider values
for the range of divider settings.
