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 speciﬁed under the following assumption: 20k < RSET ≤ 200k.

Note 3: Frequency accuracy is deﬁned 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 speciﬁcation 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 speciﬁcations which apply over the full operating

temperature range, otherwise speciﬁcations 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.

V+ = 3V

Pin 4 = V+ or Floating, RL = ∞

Pin 4 = 0V, RL = ∞

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 speciﬁcations are based on characterization.

Note 7: Guaranteed by 5V test.

Note 8: The LTC6900C is guaranteed to meet speciﬁed performance from

0°C to 70°C. The LTC6900C 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 LTC6900I is guaranteed to meet

speciﬁed performance from –40°C to 85°C.
