0.5VDC Maximum with HCMOS Load |
Defined as the Output Voltage Logic Low or "Logic 0" (Figure 1 in oscillator glossary of terms). |
|
Duty Cycle | Measured at 50% of waveform. 50 10(%) (Standard) 50 5(%) (Optional) |
The measure of output waveform uniformity. This term, also referredto as symmetry, is a measurement of the time that the outputwaveform is in a logic high state, expressed as a percentage (%).This parameter is measured at a specified voltage threshold or at apercentage of the output waveform amplitude (Figure 1 in the oscillator glossary of terms). |
|
Rise Time/Fall Time | Measured over 0.4VDC to 2.4VDC with TTL load or from 10% to 90% of waveform with HCMOS load for frequencies less than or equal to 24MHz. Measured over 10% to 90% of waveform over 24MHz. 10nSec Maximum from 250.000kHz to 24.000MHz
6nSec Maximum from 24.000001MHz to 70.000MHz
4nSec Maximum from 70.000001MHz to 125.000MHz |
The Rise Time, measured in nanoseconds (nSec), is defined as thetransition time from an output logic low to an output logic high.Conversely, the Fall Time, also measured in nanoseconds (nSec), isdefined as the transition time from an output logic high to an outputlogic low. This transition time is measured at specified voltagethresholds or at specified percentages of the output waveformamplitude (Figure 1 in the oscillator glossary of terms). |
|
Load Drive Capability | 2 TTL or 15pF HCMOS Load Maximum from 250.000kHz to 24.000MHz
15pF HCMOS Load Maximum from 24.000001MHz to 125.000MHz |
The maximum load the oscillator can drive specified in terms of thenumber of gates or the type of load circuit (Figures 2, 3 and 4 in oscillator glossary of terms). |
|
Aging (at 25C) | 5ppm/year Maximum |
The systematic change in frequency with time due to internal changes in the crystal. Aging is often expressed as a maximum value in parts per million per year (ppm/yr). The rate of aging is typically greatest during the first 30 to 60 days after which time the aging rate decreases. The following factors effect crystal aging: adsorption and desorption of contamination on the surfaces of the quartz, stress relief of the mounting and bonding structures, material outgassing, and seal integrity. |
|
Storage Temperature | -55C to +125C |
The minimum and maximum temperatures that the device can be stored or exposed to when in a non-oscillation state. After exposing or storing the device at the minimum or maximum temperatures for a length of time, all of the operating specifications are guaranteed over the specified Operating Temperature Range. |
