ELECTRICAL CHARACTERISTICS

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

frequencies, the error is specified under the following assumption:

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.

excursion.

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.
