All voltages are with respect to GND.
The

denotes the specifications which apply over the full operating
Note 1:
Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2:
Frequencies near 100kHz and 1MHz may be generated using two
different values of R
SET
(see the Table 1 in the Applications Information
section). For these frequencies, the error is specified under the following
assumption: 10k < R
SET
≤
100k.
Note 3:
Frequency error (defined as the deviation from the f
OSC
equation)
includes drift over temperature and over supply.
Note 4:
Jitter is the ratio of the peak-to-peak distribution of the period to
the mean of the period. This specification is based on characterization and
is not 100% tested.
Note 5:
Output rise and fall times are measured between the 10% and
90% power supply levels. These specifications are based on
characterization.
V
+
(Pin 1):
Voltage Supply (2.7V
≤
V
+
≤
5.5V). This supply
must be kept free from noise and ripple. It should be
bypassed directly to a ground plane.
GND (Pin 2):
Ground. Should be tied to a ground plane for
best performance.
SET (Pin 3):
Frequency-Setting Resistor Input. The value
of the resistor connected between this pin and V
+
deter-
mines the oscillator frequency. The voltage on this pin is
held by the LTC1799 to approximately 1.1V below the V
+
voltage. For best performance, use a precision metal film
resistor with a value between 10k and 200k and limit the
capacitance on this pin to less than 2pF.
DIV (Pin 4):
Divider-Setting Input. This three-state input
selects among three divider settings, determining the
value of N in the frequency equation. Pin 4 should be tied
PIU
to GND for the
÷
1 setting, the highest frequency range.
Floating Pin 4 divides the master oscillator by 10. Pin 4
should be tied to V
+
for the
÷
100 setting, the lowest
frequency range. To detect a floating DIV pin, the LTC1799
attempts to pull the pin toward midsupply. Therefore,
driving the DIV pin high requires sourcing approximately
5
μ
A. Likewise, driving DIV low requires sinking 5
μ
A.
When floated, the DIV pin will be held near midsupply by
these current sources. When it is floated, it is recom-
mended that the DIV pin be bypassed by a 1nF capacitor
or surrounded by a ground shield to prevent excessive
coupling from other PCB traces.
OUT (Pin 5):
Oscillator Output. This pin can easily drive
5k
or 10pF loads. Larger loads may cause inaccuracies
due to supply bounce at high frequencies.
