ELECTRICAL CHARACTERISTICS
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: Some frequencies may be generated using two different values of
RSET. For these frequencies, the error is specified assuming that the larger
value of RSET is used.
Note 3: Frequency accuracy is defined as the deviation from the fOUT
equation.
Note 4: Jitter is the ratio of the peak-to-peak deviation of the period to the
mean of the period. This specification is based on characterization and is
not 100% tested.
Note 5: Current into a pin is given as a positive value. Current out of a pin
is given as a negative value.
The
l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C.

Note 6: Output rise and fall times are measured between the 10% and
90% power supply levels.
Note 7: The LTC6906C is guaranteed to meet specified performance from
0°C to 70°C. The LTC6906C 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 LTC6906I is guaranteed to meet
specified performance from –40°C to 85°C.
Note 8: Consult the Applications Information section for operation with
supplies higher than 3.6V.
Note 9: Test conditions reflect the master oscillator frequency. The output
divider is functionally tested and divided frequency accuracy is guaranteed
by design.
