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: Frequencies near 100kHz and 1MHz may be generated using two
different values of RSET (see the Selecting the Divider Setting Resistor
paragraph in the Applications Information section). For these frequencies,
the error is specied under the following assumption: 20k < RSET ≤ 200k.
Note 3: Frequency accuracy is dened as the deviation from the
fOSC equation.
Note 4: Jitter is the ratio of the peak-to-peak distribution of the period to
the mean of the period. This specication 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.
The
l denotes the specications which apply over the full operating
temperature range, otherwise specications are at TA = 25°C. V+ = 2.7V to 5.5V, RL= 5k, CL = 5pF, Pin 4 = V + unless otherwise noted.
All voltages are with respect to GND.

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 specications are based on characterization.
Note 7: Guaranteed by 5V test.
Note 8: The LTC6900C is guaranteed to meet specied performance from
0°C to 70°C. The LTC6900C is designed, characterized and expected to
meet specied performance from – 40°C to 85°C but is not tested or
QA sampled at these temperatures. The LTC6900I is guaranteed to meet
specied performance from –40°C to 85°C.
