ELECTRICAL CHARACTERISTICS
LTC6902
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
frequencies, the error is specified under the following assumption:
20k < R
Note 3: Frequency accuracy is defined as the deviation from the f
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: Guaranteed by 5V test.
Note 6: To conform with the Logic IC Standard convention, current out of
a pin is arbitrarily given as a negative value.

Note 7: Output rise and fall times are measured between the 10% and the
90% power supply levels with no output loading. These specifications are
based on characterization.

Note 9: The LTC6902CMS and LTC6902IMS are guaranteed functional
over the operating temperature range of –40 C to 85 C.
Note 10: The LTC6902CMS is guaranteed to meet 0 C to 70 C specifica-
tions and are designed, characterized and expected to meet the specified
performance from –40 C to 85 C but is not tested or QA sampled at these
temperatures. The LTC6902IMS is guaranteed to meet specified perfor-
mance from –40 C to 85 C.
