LTC1799
Electrical Characteristics The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at T_A = 25°C. V⁺ = 2.7V to 5.5V, R_L = 5k, C_L = 5pF, unless otherwise noted. All
voltages are with respect to GND.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
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. The frequency accuracy for f_OSC = 20MHz
is guaranteed by design and test correlation.
Note 3: Frequency accuracy is defined as the deviation from the
f_OSC equation.
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: To conform with the Logic IC Standard convention, current out of
a pin is arbitrarily given as a negative value.
Note 6: Output rise and fall times are measured between the 10% and 90%
power supply levels. These specifications are based on characterization.
Note 7: Guaranteed by 5V test.
