Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 6:
A heat sink may be required to keep the junction temperature may cause permanent damage to the device. Exposure to any Absolute below the absolute maximum when the output is shorted indefi nitely. Maximum Rating condition for extended periods may affect device
Note 7:
The LTC6905C is guaranteed functional over the operating reliability and lifetime. temperature range.
Note 2:
Frequency accuracy is defi ned as the deviation from the fOSC
Note 8:
The LTC6905C is guaranteed to meet specifi ed performance from equation. Accuracy is tested with DIV = V+, N = 1 and other divide ratios 0°C to 70°C. The LTC6905C-XXX is designed, characterized and expected are guaranteed by design. to meet specifi ed performance from –40°C to 85°C but is not tested or QA
Note 3:
Jitter is the ratio of the peak-to-peak distribution of the period to sampled at these temperatures. The LTC6905I-XXX is guaranteed to meet the mean of the period. This specifi cation is based on characterization and specifi ed performance from –40°C to 85°C. is not 100% tested.
Note 9:
The LTC6905 is optimized for the performance with a 3V power
Note 4:
To conform with the Logic IC Standard convention, current out of supply voltage. Please consult LTC Marketing for parts optimized for 5V a pin is arbitrarily given as a negative value. operation.
Note 5:
Output rise and fall times are measured between the 10% and 90% power supply levels.
