TABLE I. Dash numbers and operating characteristics.
1/ Maximum input current for no load condition.
2/ Up to 30 days following shipment.
3/ After 30 days following shipment.
4/ See figure 3.
TABLE II. Frequency aging limits.
1/ See table I.
Initial frequency - temperature accuracy (1/2 temperature cycle): See table I. Measurements shall be taken at ten
equally spaced increments over the specified operating temperature range.
Frequency - voltage tolerance for
±10 percent change in supply voltage:
For output frequency
≤ 40.0 MHz: ±2 ppm, maximum.
For output frequency
≥ 40.0 MHz: ±4 ppm, maximum.
Frequency - environmental tolerance:
±3 ppm.
Frequency aging: Frequency aging shall be in accordance with
MIL-PRF-55310
and shall meet the limits of
table II.
