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
paragraph in the Applications Information section). For these frequencies,
the error is specified under the following assumption: 20k < R
Note 3: Frequency accuracy is defined as the deviation from the
f
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. Also, see the Peak-to-Peak Jitter vs Output Frequency
curve in the Typical Performance Characteristics section.
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.
Note 8: The LTC6900C is guaranteed to meet specified performance from
0 C to 70 C. The LTC6900C is designed, characterized and expected to
meet specified performance from – 40 C to 85 C but is not tested or QA
sampled at these temperatures. The LTC6900I is guaranteed to meet
specified performance from – 40 C to 85 C.
