ELECTRICAL CHARACTERISTICS
TYPICAL PERFOR A CE 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: LTC6908C and LTC6908I are guaranteed functional over the
operating temperature range of –40°C to 85°C.
Note 3: LTC6908C is guaranteed to meet specifi ed performance from
0°C to 70°C. The LTC6908C is designed, characterized and expected to
meet specifi ed performance from –40°C to 85°C but is not tested or QA
sampled at these temperatures. The LTC6908I is guaranteed to meet
the specifi ed performance limits from –40°C to 85°C. The LTC6908H is
guaranteed to meet the specifi ed performance limits from –40°C to 125°C.
Note 4: Frequency accuracy is defi ned as the deviation from the f
equation.
Note 5: Guaranteed by 5V test

Note 6: To conform to the Logic IC Standard, current out of a pin is
arbitrarily given 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 specifi cations are
based on characterization.
Note 8: Long term drift on silicon oscillators is primarily due to the
movement of ions and impurities within the silicon and is tested at 30°C
under otherwise nominal operating conditions. Long term drift is specifi ed
as ppm/√kHr due to the typically non-linear nature of the drift. To calculate
drift for a set time period, translate that time into thousands of hours, take
the square root and multiply by the typical drift number. For instance, a
year is 8.77kHr and would yield a drift of 888ppm at 300ppm/√kHr. Ten
years is 87.7kHr and would yield a drift of 2,809 ppm at 300 ppm/√kHr.
Drift without power applied to the device may be approximated as 1/10th
of the drift with power, or 30ppm/√kHr for a 300ppm/√kHr device.
